From: Jiajun Cao <jjcao20@fudan.edu.cn> stable inclusion from stable-5.10.52 commit fb7c8bfa2e3ca7dfc966480659961c6266336b2f bugzilla: 175542 https://gitee.com/openeuler/kernel/issues/I4DTKU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 8c13212443230d03ff25014514ec0d53498c0912 ] The function hda_tegra_first_init() neglects to check the return value after executing platform_get_irq(). hda_tegra_first_init() should check the return value (if negative error number) for errors so as to not pass a negative value to the devm_request_irq(). Fix it by adding a check for the return value irq_id.
