Subject: [ 36/95] drm/prime: Honor requested file flags when exporting a buffer

3.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Laurent Pinchart <laurent.pinchart+renesas@...asonboard.com>

commit ebc0bad4a05ad63979e8bc115cea3b8abdf814c7 upstream.

The DRM PRIME API passes file flags to the driver for the exported
buffer. Honor them instead of hardcoding 0600.
