This is a note to let you know that I've just added the patch titled ASoC: rt5663: check the return value of devm_kzalloc() in rt5663_parse_dp() to the 5.17-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: asoc-rt5663-check-the-return-value-of-devm_kzalloc-i.patch and it can be found in the queue-5.17 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 77366455d587674f3eba5cb357f8ac2eaca415e2 Author: Jia-Ju Bai <baijiaju1990@xxxxxxxxx> Date: Fri Feb 25 05:10:30 2022 -0800 ASoC: rt5663: check the return value of devm_kzalloc() in rt5663_parse_dp() [ Upstream commit 4d06f92f38b799295ae22c98be7a20cac3e2a1a7 ] The function devm_kzalloc() in rt5663_parse_dp() can fail, so its return value should be checked.
