From: Alex Deucher <alexander.deucher@amd.com> stable inclusion from stable-5.10.60 commit 95de3592f87e46df63119dd52b4a0e544e519c6b bugzilla: 177018 https://gitee.com/openeuler/kernel/issues/I4EAUG Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 202ead5a3c589b0594a75cb99f080174f6851fed upstream. If the platform uses BOCO, don't use BACO in runtime suspend. We could end up executing the BACO path if the platform supports both.
