[alsa-devel] [PATCH 2/2] ASoC: TWL4030: Convert the bitfield enums to VALUE_ENUM type

Peter Ujfalusi peter.ujfalusi at nokia.com
Mon Jan 5 08:54:58 CET 2009


Convert the bitfield coded enums to the new VALUE_ENUM type.
Remove the enum check, since the VALUE_ENUM type can handle
the bitfield coding and also handles the 'holes' in the bitfield.
