[PATCH 14/18] cx25840: Fix subdev registration in cx25840-core.c

From: Igor M. Liplianin
Date: Sat Jan 01 2011 - 04:36:23 EST


On my system, cx23885 based card reports default volume value above 70000.
So, register cx25840 subdev fails. Although, the card don't have a/v inputs
it needs a/v firmware to be loaded.
