[PATCH 05/14] drm/i915/dsb: Shuffle code around

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Relocate intel_dsb_dewake_scanline() and dsb_chicken() upwards
in the file. I need to reuse these while emitting DSB
commands, and I'd like to keep the DSB command emission
stuff more or less grouped together in the file.

Also drop the intel_ prefix from intel_dsb_dewake_scanline() since
it's all internal stuff and thus doesn't need so much namespacing.
