Subject: [ 16/55] drivers/staging/comedi/comedi_fops.c: add missing vfree

3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Julia Lawall <Julia.Lawall@...6.fr>

commit abae41e6438b798e046d721b6ccdd55b4a398170 upstream.

aux_free is freed on all other exits from the function.  By removing the
return, we can benefit from the vfree already at the end of the function.
