[PATCH 0/5] Check for valid framebuffer's format

[Maíra Canal]

This series is a follow-up of [1] in which I introduced a check for valid
formats on drm_gem_fb_create(). During the discussion, I realized that would be
a better idea to put the check inside framebuffer_check() so that it wouldn't
be needed to hit any driver-specific code path when the check fails. Thanks
to Daniel, Simon, Rob and Thomas for the insightful discussion!

Therefore, add the valid format check inside framebuffer_check() and remove
the same check from the drivers. Adding the check to framebuffer_check() will
guarantee that the igt at kms_addfb_basic@addfb25-bad-modifier IGT test passes,
showing the correct behavior of the check.

This patchset was tested on i915, amdgpu, and vc4 with the IGT tests.
