Hi Daniel, Liviu,

Having just inadvertently merged -next into my working branch, I find
dev6d910bfa809e ("drm/hlcd: Use lockless gem BO free callback") adversely
affecting my board's ability to boot ;)

Since I (intentionally) don't have sufficient CMA to create a framebuffer,
drm_gem_cma_create() fails, unconditionally calls the now-NULL
drm->driver->gem_free_object() in its cleanup path, and fiery death
ensues...

Please make sure you have the drm fixes from 4.7-rc2 included, this issue
is fixed there.
-Daniel
