[ Upstream commit e3b86f4e558cea9eed71d894df2f19b10d60a207 ]
On the case tmp_dcim=1, the index of buffer is miscalculated.
This generate a NULL pointer dereference later.
So let's fix the calcul and add a check to prevent this to reappear.

[PATCH AUTOSEL 5.17 03/66] media: staging: media: zoran: fix various V4L2 compliance errors
From: Hans Verkuil
[ Upstream commit 914941827aad5ecddf9bf3a6dee67fbec1af1fff ]
This fixes several issues found with 'v4l2-compliance -s':
1) read()/write() is supported, but not reported in the capabilities
2) S_STD(G_STD()) failed: setting the same standard should just return 0.
3) G_PARM failed to set readbuffers.
4) different field values in the format vs. what v4l2_buffer reported.
5) zero the sequence number when starting streaming.
6) drop VB_USERPTR: makes no sense with dma_contig streaming.

[PATCH AUTOSEL 5.17 21/66] media: atomisp_gmin_platform: Add DMI quirk to not turn AXP ELDO2 regulator off on some boards
From: Hans de Goede
[ Upstream commit 2c39a01154ea57d596470afa1d278e3be3b37f6a ]
The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.
Add a DMI quirk table for systems on which to leave eldo2 on.
Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

sysfs
The problem is that dummy_ptr == 0 is a valid value. So, change the logic
which checks if dummy_ptr was allocated.
At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp
reload by rmmod/insmod. Again, the check is wrong there.
So, change both checks for mmgr_EXCEPTION, which is the error value when
HMM allocation fails, and initialize dummy_ptr with such value.
[1] added on commit
d9ab83953fa7 ("media: atomisp: don't cause a warn if probe failed")
[2] added on commit
b83cc378dfc4 ("atomisp: clean up the hmm init/cleanup indirections")

[PATCH AUTOSEL 5.17 65/66] media: atomisp: fix bad usage at error handling logic
From: Mauro Carvalho Chehab
[ Upstream commit fc0b582c858ed73f94c8f3375c203ea46f1f7402 ]
As warned by sparse:
atomisp: drivers/staging/media/atomisp/pci/atomisp_acc.c:508
atomisp_acc_load_extensions() warn: iterator used outside loop: 'acc_fw'
The acc_fw interactor is used outside the loop, at the error handling
logic. On most cases, this is actually safe there, but, if
atomisp_css_set_acc_parameters() has an error, an attempt to use it
will pick an invalid value for acc_fw.

This generate a NULL pointer dereference later.

From: Hans Verkuil
[ Upstream commit 914941827aad5ecddf9bf3a6dee67fbec1af1fff ]
This fixes several issues found with 'v4l2-compliance -s':
1) read()/write() is supported, but not reported in the capabilities
2) S_STD(G_STD()) failed: setting the same standard should just return 0.
3) G_PARM failed to set readbuffers.
4) different field values in the format vs. what v4l2_buffer reported.
5) zero the sequence number when starting streaming.
6) drop VB_USERPTR: makes no sense with dma_contig streaming.

[PATCH AUTOSEL 5.16 21/59] media: atomisp_gmin_platform: Add DMI quirk to not turn AXP ELDO2 regulator off on some boards
From: Hans de Goede
[ Upstream commit 2c39a01154ea57d596470afa1d278e3be3b37f6a ]
The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.
Add a DMI quirk table for systems on which to leave eldo2 on.
Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

[PATCH AUTOSEL 5.16 22/59] media: atomisp: fix dummy_ptr check to avoid duplicate active_bo
From: Tsuchiya Yuto
[ Upstream commit 127efdbc51fe6064336c0452ce9c910b3e107cf0 ]
The dummy_ptr check in hmm_init() [1] results in the following
"hmm_init Failed to create sysfs" error exactly once every
two times on atomisp reload by rmmod/insmod (although atomisp module
loads and works fine regardless of this error):

sysfs
The problem is that dummy_ptr == 0 is a valid value. So, change the logic
which checks if dummy_ptr was allocated.
At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp
reload by rmmod/insmod. Again, the check is wrong there.
So, change both checks for mmgr_EXCEPTION, which is the error value when
HMM allocation fails, and initialize dummy_ptr with such value.
[1] added on commit
d9ab83953fa7 ("media: atomisp: don't cause a warn if probe failed")
[2] added on commit
b83cc378dfc4 ("atomisp: clean up the hmm init/cleanup indirections")

[PATCH AUTOSEL 5.16 58/59] media: atomisp: fix bad usage at error handling logic
From: Mauro Carvalho Chehab
[ Upstream commit fc0b582c858ed73f94c8f3375c203ea46f1f7402 ]
As warned by sparse:
atomisp: drivers/staging/media/atomisp/pci/atomisp_acc.c:508
atomisp_acc_load_extensions() warn: iterator used outside loop: 'acc_fw'
The acc_fw interactor is used outside the loop, at the error handling
logic. On most cases, this is actually safe there, but, if
atomisp_css_set_acc_parameters() has an error, an attempt to use it
will pick an invalid value for acc_fw.

From: Corentin Labbe
[ Upstream commit e3b86f4e558cea9eed71d894df2f19b10d60a207 ]
On the case tmp_dcim=1, the index of buffer is miscalculated.
This generate a NULL pointer dereference later.
So let's fix the calcul and add a check to prevent this to reappear.

From: Hans Verkuil
[ Upstream commit 914941827aad5ecddf9bf3a6dee67fbec1af1fff ]
This fixes several issues found with 'v4l2-compliance -s':
1) read()/write() is supported, but not reported in the capabilities
2) S_STD(G_STD()) failed: setting the same standard should just return 0.
3) G_PARM failed to set readbuffers.
4) different field values in the format vs. what v4l2_buffer reported.
5) zero the sequence number when starting streaming.
6) drop VB_USERPTR: makes no sense with dma_contig streaming.

[PATCH AUTOSEL 5.15 20/50] media: atomisp_gmin_platform: Add DMI quirk to not turn AXP ELDO2 regulator off on some boards
From: Hans de Goede
[ Upstream commit 2c39a01154ea57d596470afa1d278e3be3b37f6a ]
The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.
Add a DMI quirk table for systems on which to leave eldo2 on.
Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

sysfs
The problem is that dummy_ptr == 0 is a valid value. So, change the logic
which checks if dummy_ptr was allocated.
At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp
reload by rmmod/insmod. Again, the check is wrong there.
So, change both checks for mmgr_EXCEPTION, which is the error value when
HMM allocation fails, and initialize dummy_ptr with such value.
[1] added on commit
d9ab83953fa7 ("media: atomisp: don't cause a warn if probe failed")
[2] added on commit
b83cc378dfc4 ("atomisp: clean up the hmm init/cleanup indirections")

[PATCH AUTOSEL 5.15 49/50] media: atomisp: fix bad usage at error handling logic
From: Mauro Carvalho Chehab
[ Upstream commit fc0b582c858ed73f94c8f3375c203ea46f1f7402 ]
As warned by sparse:
atomisp: drivers/staging/media/atomisp/pci/atomisp_acc.c:508
atomisp_acc_load_extensions() warn: iterator used outside loop: 'acc_fw'
The acc_fw interactor is used outside the loop, at the error handling
logic. On most cases, this is actually safe there, but, if
atomisp_css_set_acc_parameters() has an error, an attempt to use it
will pick an invalid value for acc_fw.

2) S_STD(G_STD()) failed: setting the same standard should just return 0.
3) G_PARM failed to set readbuffers.
4) different field values in the format vs. what v4l2_buffer reported.
5) zero the sequence number when starting streaming.
6) drop VB_USERPTR: makes no sense with dma_contig streaming.

[PATCH AUTOSEL 5.10 13/37] media: atomisp_gmin_platform: Add DMI quirk to not turn AXP ELDO2 regulator off on some boards
From: Hans de Goede
[ Upstream commit 2c39a01154ea57d596470afa1d278e3be3b37f6a ]
The TrekStor SurfTab duo W1 10.1 has a hw bug where turning eldo2 back on
after having turned it off causes the CPLM3218 ambient-light-sensor on
the front camera sensor's I2C bus to crash, hanging the bus.
Add a DMI quirk table for systems on which to leave eldo2 on.
Note an alternative fix is to turn off the CPLM3218 ambient-light-sensor
as long as the camera sensor is being used, this is what Windows seems
to do as a workaround (based on analyzing the DSDT). But that is not
easy to do cleanly under Linux.

sysfs
The problem is that dummy_ptr == 0 is a valid value. So, change the logic
which checks if dummy_ptr was allocated.
At this point, atomisp now gives WARN_ON() in hmm_free() [2] on atomisp
reload by rmmod/insmod. Again, the check is wrong there.
So, change both checks for mmgr_EXCEPTION, which is the error value when
HMM allocation fails, and initialize dummy_ptr with such value.
[1] added on commit
d9ab83953fa7 ("media: atomisp: don't cause a warn if probe failed")
[2] added on commit
b83cc378dfc4 ("atomisp: clean up the hmm init/cleanup indirections")

[PATCH AUTOSEL 5.10 36/37] media: atomisp: fix bad usage at error handling logic
From: Mauro Carvalho Chehab
[ Upstream commit fc0b582c858ed73f94c8f3375c203ea46f1f7402 ]
As warned by sparse:
atomisp: drivers/staging/media/atomisp/pci/atomisp_acc.c:508
atomisp_acc_load_extensions() warn: iterator used outside loop: 'acc_fw'
The acc_fw interactor is used outside the loop, at the error handling
logic. On most cases, this is actually safe there, but, if
atomisp_css_set_acc_parameters() has an error, an attempt to use it
will pick an invalid value for acc_fw.
