Subject: drm/i915/selftests: cond_resched() within the longer buddy tests
Git-commit: e7b6affd0baef7b3c5e2acd94236093dcf437105
Patch-mainline: v5.5-rc1
References: bsc#1152489
Let the scheduler have a breather in between passes of the longer buddy
tests. Important if we are running under kasan etc and this takes far
longer than usual!
