Step config setting for 5 wire touchscreen is incorrect for Y coordinates.
It was broken while we moved to DT. If you look close at the offending
commit bb76dc09ddfc ("input: ti_am33x_tsc: Order of TSC wires, made
configurable"), the change was:

The hm->h.size is intended to hold the actual size of the hm struct

However, after copy_from_user(hm, puhm, hm->h.size), since userspace

possible that the value

The reported scale was only correct for the default settings of 100 ms
integration time and gain 1.
This aligns the reported scale with the behaviour of any other IIO driver
and the documented ABI, but may require userspace changes if someone uses
non-default settings.

This improves code uniformity (range checks for als_gain are also done

Currently, the vl6180 driver reports bogus in_illuminance_scale values
when the integration time or hardware gain are changed from its default
value, i.e. it always reports a fixed value.
To avoid readback of the register values in case integration time, gain
or scale is queried, save the register
Instead of manually iterating the array of allowed gain values, use
find_closest. Storing the current gain setting avoids accessing the
hardware on each query.

Sorry for being late to the party…
I tried to use this patch backported to 4.9.49 but could only get the system to
reset (presumably the SMI but not certain since I’m not that current on BMC/SMI
architecture) when it hung.
It’s a Lanner FW-8771 with AMI BIOS 4.6.5 on a Xeon E3-1225 v3.

Sure I can pick them up through cryptodev.

v2:
- Add missing include in xen patch 7/8
Add some annotations to allow objtool to understand the head code.
Among other things, this allows the ORC unwinder to completely unwind an
idle task.
Also do a few cleanups while I'm there.
Josh Poimboeuf (8):
objtool: Don't report end of section err
This comment is actively wrong and confusing. It refers to the
registers' stack offsets after the pt_regs has been constructed on the
stack, but this code is *before* that.
At this point the stack just has the standard iret frame, for which no
comment should be needed.

Add unwind hint annotations to the xen head code so the ORC unwinder can
read head_64.o.
hypercall_page needs empty annotations at 32-byte intervals to match the
'xen_hypercall_*' ELF functions at those locations.

If asm code specifies an UNWIND_HINT_EMPTY hint, don't warn if the
section ends unexpectedly. This can happen with the xen-head.S code
because the hypercall_page is "text" but it's all zeros.

For the testing, I found handle passed to zs_map_object in __zram_bvec_read
is NULL so that kernel goes the oops by pin_object.
The reason is there is no routine to check the slot's freeing
after getting the slot's lock. This patch fixes it.
