HI ,
Is there any known issue of slab poisoning in binder_transaction variable on
kernel 4.9,
it seems owner variable of spinlock is
getting corrupted(which is last 8th byte of binder_transaction struct).

Use eth_zero_addr to assign zero address to the given address array
instead of memset when the second argument in memset is address
of zero. Coccinelle was used to do the replacement and add the
header file linux/etherdevice.h if not already present.
The Coccinelle semantic patch that makes this c
Not all errors that occurred in tsl2x7x_get_prox() were correctly
reported in the return value. This patch changes the error handling
so that errors are now returned properly.
Note that the ret variable is from the call to tsl2x7x_read_status(),
and it already has the correct error check. The -EIN
The tsl2771 and tmd2771 devices create the
in_proximity0_calibscale_available sysfs attribute. These two particular
devices do not support changing the proximity gain value on the
chip so this patch removes that sysfs attribute. As expected, these two
devices already did not create the IIO_CHAN_INF
The tsl2X7X_platform_data structure contains the platform_power,
power_on, and power_off function pointers. These power management
functions should not be in the platform data. These functions were
likely used before the regulator framework was put in place. There are
no users of these functions in
The driver uses mutex_lock() and mutex_trylock() in several places.
Convert the mutex_trylock() to mutex_lock() for consistency with other
IIO light drivers in mainline.

There were four places where the same chunk of code was used to write
to the control register. This patch creates a common function
tsl2x7x_write_control_reg() to reduce duplicate code.
The function tsl2x7x_chip_off() did not correctly return an error
code so this patch also corrects that issue.
There were three places where the same chunk of code was used to clear
interrupts. This patch creates a common function
tsl2x7x_clear_interrupts() to reduce duplicate code.

This patch updates all of the logging commands so that they are

This patch also removes some debug log messages from tsl2x7x_prox_cal().

Here is another patch series that inches the driver closer to moving out
of staging. The most interesting changes are the last two in the series.
One gets the proximity sensor working and the other one removes the

The bits for setting up the proximity diode were not setup correctly and
this was causing the proximity sensor to not function correctly. This
patch sets up the correct bit mask in tsl2x7x_chip_on() based on what
the data sheet expects. From page 35 of the TSL2771 data sheet:

There were three places where the same chunk of code was used to read
the chip status. This patch creates a common function
tsl2x7x_read_status() to reduce duplicate code. This patch also corrects
tsl2x7x_event_handler() to properly check for an error after reading the
chip status.
