From: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@xxxxxxxxx>
Commit 5ce6861d36ed5207aff9e5eead4c7cc38a986586 upstream.
This backport targets stable version 5.4, since the original patch fails
to apply there, due to a variable having moved from one struct to another.
The only change required for the patch to apply to 5.4 is to use the
correct structure:
- (engine->gt->info.vdbox_sfc_access &
++ (RUNTIME_INFO(i915)->vdbox_sfc_access &
Original commit message below.
SFC capability of video engines is not set correctly because i915
is testing for incorrect bits.
