This is a note to let you know that I've just added the patch titled
iio: adc: xilinx-ams: fix devm_krealloc() return value check
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 6794ed0cfcc6ce737240eccc48b3e8190df36703 Mon Sep 17 00:00:00 2001 From: Marco Pagani marpagan@redhat.com Date: Fri, 25 Nov 2022 12:31:12 +0100 Subject: iio: adc: xilinx-ams: fix devm_krealloc() return value check
The clang-analyzer reported a warning: "Value stored to 'ret' is never read".
Fix the return value check if devm_krealloc() fails to resize ams_channels.
