Subject: drm/i915: Use DPINVGTT_STATUS_MASK
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7c4cde39684cffc6aaae4f34f2bcd987a86befe6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Use DPINVGTT_STATUS_MASK

Some has given a name for the DPINVGTT status bitmask, so let's use it
instead of the magic number. Looks more like the chv code now.
