stable inclusion from stable-5.10.52 commit 32064330708b7bf4122ab163a8c9b29e91afd6b9 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 35564e2bf94611c3eb51d35362addb3cb394ad54 ]
When external RT714/715 devices are used for capture, we don't want the PCH DMICs to be used.
Any information provided by the SOF platform driver or DMI quirks will be overridden.
