Subject: [PATCH 3/3] [media] au0828-video: Move two assignments in
 au0828_init_isoc()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 24 Oct 2016 22:44:02 +0200

Move the assignment for the data structure members "isoc_copy"
and "num_bufs" behind the source code for memory allocations
by this function.
