This is a note to let you know that I've just added the patch titled
iio: adc: ti-ads1298: Add NULL check in ads1298_init
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 bcb394bb28e55312cace75362b8e489eb0e02a30 Mon Sep 17 00:00:00 2001 From: Charles Han hanchunchao@inspur.com Date: Mon, 18 Nov 2024 17:02:08 +0800 Subject: iio: adc: ti-ads1298: Add NULL check in ads1298_init
devm_kasprintf() can return a NULL pointer on failure. A check on the return value of such a call in ads1298_init() is missing. Add it.
