[Intel-gfx] [PATCH 07/19] drm/tegra: Don't use modeset_lock_crtc

[Daniel Vetter]

Yes the help text is unhelpful, but atomic drivers should never use
this. Just grab the lock without context or anything.

Also an aside: Checking ->active like this doesn't protect against
nonblocking commits, this is rather bogus.
