From c888923debf8c8a799629f77d07aeb0f8350c87b Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Sun, 15 Mar 2009 17:38:47 -0300 Subject: [PATCH] V4L/DVB (11082): au0828: remove memset calls in v4l2 routines. The userland callers are responsible for clearing the output buffers, so remove the unneeded memset calls. Thanks to Mauro Carvalho Chehab for pointing this out.
