[PATCH] staging: media: as102: replace custom dprintk() with dev_dbg()

From: Martin Kepplinger
Date: Sun Aug 03 2014 - 10:56:05 EST


remove dprintk() and replace it with dev_dbg() in order to
use the common kernel coding style.

I don't have the device but this builds.
I think this is ok when it gets reviewed.
