[PATCH 1/2] drm/i915: Make for_each_plane() take dev_priv as argument

[Damien Lespiau <damien.lespiau@xxxxxxxxx>]

Implicit usage of local variables in macros isn't exactly the greatest
thing in the world, especially when that variable is the drm device and
we want to move towards a broader use of the i915 device structure.

Let's make for_each_plane() take dev_priv as its first argument then.
