Re: [Intel-gfx] [PATCH] drm/i915: Increase max texture to 16k for gen9+

Thanks for comment. I'm not familiar with that, so just followed the patch in mes https://patchwork.freedesktop.org/patch/124918/a.

How about change subtitle to "drm/i915: Increase max CRTC bounds to 16k for gen9+"?

These are nothing to do with texture size, but single CRTC bounds. -Chris
