Subject: drm/exynos: remove function check_gem_flags
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c4130bcd6a80f29a5d0cabcef8f0341cfa812dff;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/exynos: remove function check_gem_flags

The function check_gem_flags is too simple, so it's better to move codes
in each consumer functions.
