[PATCH 5.15 084/128] platform/x86: amd-pmc: only use callbacks for suspend

From: Greg Kroah-Hartman
Date: Mon Dec 27 2021 - 10:47:32 EST


From: Mario Limonciello <mario.limonciello@xxxxxxx>

commit 09fc14061f3ed28899c23b8714c066946fdbd43e upstream.

This driver is intended to be used exclusively for suspend to idle
so callbacks to send OS_HINT during hibernate and S5 will set OS_HINT
at the wrong time leading to an undefined behavior.
