From 6c43a2178e02d41c89b93025257317d299b9e4a4 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 30 Nov 2015 18:08:10 -0200 Subject: [PATCH] [media] cx23885: add support for ViewCast 260e and 460e Add support for these two new cards. Based upon Devin's initial patch made for an older kernel which I cleaned up and rebased. Thanks to Kernel Labs for that work.
