Subject: [Patch 07/20] V4L(907) Em28xx cleanups and fixes
Date: Mon, 07 Nov 2005 00:58:08 -0200 [thread overview]
Message-ID: <1131333341.25215.12.camel@localhost> (raw)
[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 19623 bytes --]
From: Mauro Carvalho Chehab <mchehab@brturbo.com.br>
- Em28xx cleanups and fixes.
- Some cleanups and audio amux adjust.
- em28xx will allways try, by default, the biggest size alt.
- Fixes audio mux code.
- Fixes some logs.
- Adds support for digital output for WinTV USB2 board.
