drm/kms: move driver specific fb common code to helper functions (v2)
Initially I always meant this code to be shared, but things ran away from me before I got to it. This refactors the i915 and radeon kms fbdev interaction layers out into generic helpers + driver specific pieces. It moves all the panic/sysrq enhancements to the core file, and stores a linked list of kernel fbs. This could possibly be improved to only store the fb which has fbcon on it for panics etc. radeon retains some specific codes used for a big endian workaround. changes: fix oops in v1 fix freeing path for crtc_info Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
