iio: pressure: zpa2326: Use aligned_s64 for the timestamp

2025-07-06T09:04:06Z

[ Upstream commit 886a446b76afddfad307488e95e87f23a08ffd51 ] On x86_32 s64 fields are only 32-bit aligned. Hence force the alignment of the field and padding in the structure by using aligned_s64 instead.

iio: pressure: mprls0025pa: use aligned_s64 for timestamp

2025-04-21T10:51:48Z

Follow the pattern of other drivers and use aligned_s64 for the timestamp. This will ensure the struct itself it also 8-byte aligned. While touching this, convert struct mpr_chan to an anonymous struct to consolidate the code a bit to make it easier for future readers.

iio: pressure: zpa2326: Drop unneeded assignment for cache_type

2025-02-08T15:16:30Z

REGCACHE_NONE is the default type of the cache when not provided. Drop unneeded explicit assignment to it. Note, it's defined to 0, and if ever be redefined, it will break literally a lot of the drivers, so it very unlikely to happen.

iio: pressure: Use aligned_s64 instead of open coding alignment.

2024-12-28T14:28:15Z

Use this new type to both slightly simplify the code and avoid confusing static analysis tools. Mostly this series is about consistency to avoid this code pattern getting copied into more drivers.

Move sleep functions to the new fsleep() implementation. While at it, add time unit abbreviation as a suffix of time describing variables to make them more intuitive.

iio: bm1390: simplify using guard(mutex)

2024-12-07T17:47:58Z

The BM1390 uses mutex for protecting the fifo read sequence. The clean-up for a few of the functions can be slightly simplified by removing the goto-based error handling/unlocking and by utilizing the guard(mutex) scoped mutex handling instead. Simplify driver by using the scoped mutexes.

iio: pressure: zpa2326: fix information leak in triggered buffer

2024-12-07T17:23:42Z

The 'sample' local struct is used to push data to user space from a triggered buffer, but it has a hole between the temperature and the timestamp (u32 pressure, u16 temperature, GAP, u64 timestamp). This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.
