category: bugfix

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=413638f61501c9e2a592a5846a789968cd7b39a6



--------------------------------

[ Upstream commit d3de5616 ]

After applying an engine reset, on some platforms like Jasperlake, we
occasionally detect that the engine state is not cleared until shortly
after the resume. As we try to resume the engine with volatile internal
state, the first request fails with a spurious CS event (it looks like
it reports a lite-restore to the hung context, instead of the expected
idle->active context switch).
