[Intel-gfx] [PATCH] drm/i915: Use extended power domain bitmask

Daniel Stone daniels at collabora.com
Thu Nov 5 08:55:27 PST 2015


c4111f0ac6 extended the size of the power-domain enum to 64 bits wide,
but there are still a few 'unsigned long' users inside intel_display.c.

Make these unsigned long long so we can also capture DRIVER_MODESET,
and use this to simplify the modeset power domain handling a little.

[daniels: New; only required when working against Patrik/Imre's tree.]
