Subject: drm/i915: Only run commit when crtc is active, v2.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6285262259ca3d12da57073236a55d1b81bf8643;p=linux-beck.git

drm/i915: Only run commit when crtc is active, v2.

The crtc->active guards are no longer needed now that all state
updates are outside the commit.

Changes since v1:
- Only check crtc->state->active before calling commit_planes_on_crtc.
