Subject: [PATCH] em28xx: remove dead code line from em28xx_audio_setup()
Date: Sat, 13 Sep 2014 10:56:46 +0200 [thread overview]
Message-ID: <1410598606-889-1-git-send-email-fschaefer.oss@googlemail.com> (raw)
Setting the value of the chip config register to EM28XX_CHIPCFG_AC97 in case of
a read error is a leftover from the past which is no longer needed.
