From d9bdf77296a00538faff95f29bf238857daea2e7 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Tue, 26 Dec 2006 07:33:48 -0300 Subject: [PATCH] V4L/DVB (5011): DVB: Remove unneeded void * casts in ttpci/av7110 The patch removes unneeded void * casts for the following (void *) pointers: - struct file: private_data - struct dvb_device: priv - struct dvb_demux: priv - struct dvb_adapter: priv The patch also contains some whitespace and coding style cleanups in the relevant areas.
