Dear all,
This patchset performs a significant cleanup of Exynos DRM code. This includes the following 2 big items: - the custom 'sub-driver' framework has been finally replaced by generic device component code; - access to exynos GEM object has been simplified and unified.
Best regards Marek Szyprowski Samsung R&D Institute Poland
Patch summary:
Marek Szyprowski (4): drm/exynos: g2d: Convert to driver component API drm/exynos: gem: Simplify access to exynos GEM objects drm/exynos: Use common exynos_drm_gem_get()/put() functions for GEM lookup drm/exynos: gem: Switch to drm_gem_object_put_unlocked() helper

Exynos G2D driver is the last client of the custom Exynos 'sub-driver' framework. In the current state it doesn't really resolve any of the issues it has been designed for, as Exynos DRM is already built only as a single kernel module. Remove the custom 'sub-driver' framework and simply use generic component framework also in G2D driver.
