[Intel-gfx] [PATCH v3 2/6] drm/i915: Flatten a bunch of the pfit functions

Wed Apr 22 16:19:13 UTC 2020
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Most of the pfit functions are of the form:
func()
{
if (pfit_enabled) {
...
}
}
Flip the pfit_enabled check around to flatten the functions.
And while we're touching all this let's do the usual
s/pipe_config/crtc_state/ replacement.
