[PATCH OLK-6.6] ASoC: Intel: bytcr_rt5651: Fix invalid quirk input mapping
by z00845436 22 Nov '25

22 Nov '25

From: Takashi Iwai <tiwai(a)suse.de> mainline inclusion from mainline-v6.18-rc1 commit 4336efb59ef364e691ef829a73d9dbd4d5ed7c7b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID6BB3 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------- When an invalid value is passed via quirk option, currently bytcr_rt5640 driver just ignores and leaves as is, which may lead to unepxected results like OOB access. This patch adds the sanity check and corrects the input mapping to the certain default value if an invalid value is passed.
