This is a note to let you know that I've just added the patch titled
iio: pressure: mprls0025pa: use aligned_s64 for timestamp
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.
From ffcd19e9f4cca0c8f9e23e88f968711acefbb37b Mon Sep 17 00:00:00 2001 From: David Lechner dlechner@baylibre.com Date: Fri, 18 Apr 2025 11:17:14 -0500 Subject: iio: pressure: mprls0025pa: use aligned_s64 for timestamp
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.
