Linux 6.12-rc2
Resolved movement of asm/unaligned.h to linux/unaligned.h
|
|
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.
auto-generated by the following:
for i in `git grep -l -w asm/unaligned.h`; do
sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
done
for i in `git grep -l -w asm-generic/unaligned.h`; do
sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i
done
git mv include/asm-generic/unaligned.h include/linux/unaligned.h
git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h
sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild
sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

'struct iio_map' are not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
In order to do it, the prototype of iio_map_array_register() and
devm_iio_map_array_register(), and a few structures that hold a
"struct iio_map *" need to be adjusted.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
21086 760 0 21846 5556 drivers/iio/adc/axp20x_adc.o
After:
=====
text data bss dec hex filename
21470 360 0 21830 5546 drivers/iio/adc/axp20x_adc.o
33842 1697 384 35923 8c53 drivers/iio/addac/ad74413r.o

Instead of using regmap_update_bits() and passing val = 0, use
regmap_clear_bits().

wait_for_completion_interruptible_timeout()
There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_interruptible_timeout() causing patterns like:
timeout = wait_for_completion_interruptible_timeout(...)
if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.

Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.
The ultimate goal is to actually drop of.h from iio.h.

The only call in the remove hook is the iio_map_array_unregister() call.
Since we have a devm_iio_map_array_register() function now, we can use that
and remove the remove hook entirely.
The IIO device was registered with the devm_iio_device_register() prior to
this change.
Also, the platform_set_drvdata() can be removed now, since it was used only
in the remove hook.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

There is no need to call unaligned helpers on stack placed variables
because compiler will align them correctly, accordingly to architectural
ABI. Moreover, using bitwise type makes it explicit to see what we are
reading in bulk transfer. On top of that, use sizeof() instead of
magic value.

This probe function is passing the wrong size to devm_iio_device_alloc().
It is supposed to be the size of the private data. Fortunately,
sizeof(*indio_dev) is larger than sizeof(struct mrfld_adc) so it doesn't
cause a runtime problem.
