Hi Maxime,
This is the first bunch of fixes for the sun4i drm driver. This is part
of the cleanup I am doing towards making the driver support multiple
display pipelines.
Patch 1 moves the drm_mode_config_cleanup call from sun4i_framebuffer_free
to be called directly in sun4i_drv_unbind. This is needed for patch 2, so
it doesn't get called twice.
Patch 2 adds proper clean up to the error return path in sun4i_drv_bind.
Patch 3 adds a check for drm_vblank_init's return value. It can fail if
no memory is available.
Patch 4 fixes the element size passed to kcalloc. Previously we were
allocating too much memory.
Patch 5 drops a useless assignment.
Patch 6 makes sun4i_layers_init actually store the created layers in the
list that it returns. This one was particularly nasty.
Patch 7 makes sun4i_crtc_init pass back error codes.
We probably don't need to tag stable for these. Patch 1 and 2 fix up
possible memory and object leakage, but unless the user keeps unloading
and loading the modules, it won't leak past a few times.
Regards
ChenYu
