drm/cirrus: Use drm_framebuffer_put to avoid kernel oops in clean-up

2019-04-20T07:16:00+00:00

[ Upstream commit abf7b30d7f61d981bfcca65d1e8331b27021b475 ] In the Cirrus driver, the regular clean-up code also performs the clean-up of a failed initialization. If the fbdev's framebuffer was not initialized, the clean-up will fail within drm_framebuffer_unregister_private. Booting with cirrus.bpp=16 triggers this bug. The framebuffer is currently stored directly within struct cirrus_fbdev. To fix the bug, we turn it into a pointer that is only set for initialized framebuffers. The fbdev's clean-up code skips uninitialized framebuffers. The memory for struct drm_framebuffer is allocated dynamically. This requires additional error handling within cirrusfb_create. The framebuffer clean-up is now performed by drm_framebuffer_put, which also frees the data strcuture's memory.

drm: drop _mode_ from drm_mode_connector_attach_encoder

Now cirrus_framebuffer is just an empty wrapper around drm_framebuffer, we can drop it.

drm/cirrus: Place GEM BOs in drm_framebuffer

2018-05-18T13:52:18+00:00

Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those.
