Subject[PATCH 4.7 137/143] ALSA: line6: Remove double line6_pcm_release() after failed acquire.
Date
4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrej Krutak <dev@andree.sk>

commit 7e4379eae0e31994ea645db1d13006ea8e5ce539 upstream.

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

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