Some urgent regression fixes to booting failures Exynos DRM occured. Summary: - Fix two urgent null pointer dereference bugs in case of enabling or disabling IOMMU. There was two cases to these issues. One is that plane->crtc is accessed by exynos_disable_plane() when device tree binding is broken so device driver tries to release, which means that the mode set operation isn't invoked yet so plane->crtc is still NULL and exynos_disable_plane() will access NULL pointer. This issue is fixed by checking if the plane->crtc is NULL or not in exynos_disable_plane() Other is that fimd_wait_for_vblank() is called to avoid from page fault with IOMMU before the ctx object is created. At this time, fimd_wait_for_vblank() tries to access ctx->crtc but the ctx->crtc is still NULL because exynos_drm_crtc_create() isn't called yet. This issue is fixed by creating a crtc object and setting it to ctx->crtc prior to fimd_wait_for_vblank() call. For more details, you can refer to below an e-mail thread, http://www.spinics.net/lists/linux-samsung-soc/msg42436.html - Remove unnecessary file not used and fix trivial issues. * 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos: drm/exynos: fix the initialization order in FIMD drm/exynos: fix typo config name correctly. drm/exynos: Check for NULL dereference of crtc drm/exynos: IS_ERR() vs NULL bug drm/exynos: remove unused files
