[PATCH v3 13/13] drm/i915/audio: Clean up the PCH type checks

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Use explicit PCH type checks to make it more clear
which platforms use which codepaths.

Also reorder the branches in ibx_audio_regs_init()
a bit to be more in chronological order.
