Subject: drm/i915: Pass the actual sprite width to watermarks functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=67ca28f30af8e7555f40b916c28148b432168eec;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Pass the actual sprite width to watermarks functions

Don't subtract one from the sprite width before watermark calculations.
