[Intel-gfx] [PATCH 05/15] drm/i915: Flatten a bunch of the pfit functions
Ville Syrjala

Wed Sep 4 16:26:15 UTC 2019
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.
