[PATCH 7/7] headers: Update drm.h

Daniel Vetter daniel.vetter at ffwll.ch
Wed Mar 30 15:04:42 UTC 2016


This needs the kernel patch to make sure the C++ protection is in place.

Otherwise just new defines, using the right fixed-width types and
some shuffling in where stuff is defined (the DRM_CAP list moved, but
the #defines are the same).

Generated using make headers_install.
