X-Git-Tag: microblaze-v5.18~26^2~28^2~27
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=86a9bb5bf9f610ea6baa855b4f46ecea92876ea4;p=linux-2.6-microblaze.git

ALSA: usb-audio: Drop CONFIG_PM ifdefs

Practically seen, CONFIG_PM is almost mandatory.
Let's drop the ugly ifdef lines and simplify the code.
