Subject: drm/i915: No-Op enter/leave vt gem ioctl
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=71b14ab6184cc618d4c3557205113d3df51e2197;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: No-Op enter/leave vt gem ioctl

We've killed ums support by now, it's time to reap the benefits. This
one here is getting in the way of doing some ring init cleanup.
