Subject: ALSA: ump: Drop redundant check of note-on with zero velocity
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ab2335daa6ef70df56c98c216261a93e28ae52b3;p=linux.git

ALSA: ump: Drop redundant check of note-on with zero velocity

The check of a note-on event with zero velocity is done twice, and the
latter one is superfluous.  Let's drop it.
