Subject: ALSA: line6: Remove double line6_pcm_release() after failed acquire.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e4379eae0e31994ea645db1d13006ea8e5ce539;p=linux-beck.git

ALSA: line6: Remove double line6_pcm_release() after failed acquire.

If there's an error, pcm is released in line6_pcm_acquire already.

Fixes: 247d95ee6dd2 ('ALSA: line6: Handle error from line6_pcm_acquire()')
