Subject: drm/xe/tests: Grab a memory access reference around the migrate sanity test
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=907a319c8c8e125224b088f91f468f549f1e1da7;p=linux.git

drm/xe/tests: Grab a memory access reference around the migrate sanity test

It appears we don't hold a memory access reference for the accesses in
this test, which may results in printed warnings and possibly the GT
not woken up for the memory accesses.

Add a memory access reference around the test.
