Fix memory leak in dvr open
From: Trent Piepho <xyzzy@speakeasy.org>
The dvr device could be opened multiple times simultaneously in O_RDONLY mode.
Each open after the first would allocate a new dvr buffer (1880 KB) and leak
the old buffer. The first close would de-allocate the dvr buffer and cause
all other open dvrs to stop working. This patch allows only a single O_RDONLY
open of the drv device, as per the API specification. Multiple O_WRONLY opens
are still allowed and don't appear to cause any problems.
