Subject: Re: [PATCH] V4L: em28xx: add support for Digitus/Plextor PX-AV200U
Hi all,
Is there any reason why this patch was not merged into the mainline
kernel branch? I own a Plextor PX AV200U, and I can confirm that this
code does indeed work: I can capture both video and audio from the
card, and I would be very grateful if it could be merged.
Of course, it needs a little tweaking to get it to run in 4.xx
kernels. For one thing, the assigned id-number (59) has by now been
taken by another board, but I simply used the next available id as
found in em28xx.h (98 in kernel 4.1.12). Also some constants appear to
have changed name, and a few files were moved around since this patch
was originally posted.
Below is my tweaked patch, which I applied to kernel 4.1.12.
Is there some way to get this feature merged into the mainline branch?
Kind regards,
James Bates
