Ivan Abramov b05b5627f0 drm/gma500: Add NULL check for pci_gfx_root in mid_get_vbt_data() 
[ Upstream commit 9af152dcf1a06f589f44a74da4ad67e365d4db9a ]

Since pci_get_domain_bus_and_slot() can return NULL, add NULL check for
pci_gfx_root in the mid_get_vbt_data().

This change is similar to the checks implemented in mid_get_fuse_settings()
and mid_get_pci_revID(), which were introduced by commit 0cecdd818c
("gma500: Final enables for Oaktrail") as "additional minor
bulletproofing".

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: f910b41105 ("gma500: Add the glue to the various BIOS and firmware interfaces")
