Subject: drm/xe/selftests: hold rpm for ccs_test_migrate()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=939902913a25a0feaa9ca34969dd7e5b43fc2502;p=linux.git

drm/xe/selftests: hold rpm for ccs_test_migrate()

The GPU job will keep the device awake, however assumption here is that
caller of xe_migrate_clear() is also holding mem_access.ref otherwise we
hit the asserts in xe_sa_bo_flush_write() prior to the job construction.
