Subject: [PATCH 06/17] cx23885: Add a VIDIOC_LOG_STATUS ioctl function for analog video devices
Date: Mon, 19 Jul 2010 21:12:51 -0400 [thread overview]
Message-ID: <1279588371.28153.8.camel@localhost> (raw)
In-Reply-To: <cover.1279586511.git.awalls@md.metrocast.net>
Add a simple log_status function for raw analog video capture device nodes,
to provide insight into the state of the CX2388[578] A/V decoder core.
