Subject[PATCH 5.4 47/80] drm/mgag200: Store flags from PCI driver data in device structure
Date
From: Thomas Zimmermann <tzimmermann@suse.de>

commit d6d437d97d54c85a1a93967b2745e31dff03365a upstream.

The flags field in struct mga_device has been unused so far. We now
use it to store flag bits from the PCI driver.
