Subject: drm/exynos: Remove exynos_gem from struct exynos_drm_fbdev
X-Git-Tag: v6.6.17~4917^2~5^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=89c258b5226d86a5d57b6df17eec00ab0f3d5b80;p=platform%2Fkernel%2Flinux-rpi.git

drm/exynos: Remove exynos_gem from struct exynos_drm_fbdev

Fbdev's framebuffer stores a pointer to the GEM object. Remove
struct exynos_drm_fbdev.exynos_gem, which contains the same value.
No functional changes.
