Subject: drm/i915: Remove one level of indention from wait-for-execute
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f2f61d4a8d4611155e7d1633db271ead9057981;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Remove one level of indention from wait-for-execute

Now that the code is getting simpler, we can reduce the indentation when
waiting for the global_seqno.
