drm/selftests: Add tests for drm_internal_framebuffer_create
Browse files Browse the repository at this point in the history 
Add tests that verify that drm_internal_framebuffer_create creates
buffers correctly by creating a dummy drm_device with a mock function
for the fb_create callback.

To decide if a buffer has been created or not it just checks if
fb_create callback has been called for the particular drm_mode_fb_cmd2
that's being tested.
