Subject: ALSA: ps3: Use WARN_ON() instead of BUG_ON()
X-Git-Tag: v3.13-rc1~122^2~24
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=025be74c1db44158dd3cfe43b89ba16266d01062;p=karo-tx-linux.git

ALSA: ps3: Use WARN_ON() instead of BUG_ON()

BUG_ON() is rather useless for debugging as it leads to panic().
Use WARN_ON() and handle the error cases accordingly.
