Subject: Fw: [PATCH 34/52] devices.txt: add video4linux device for Software
 Defined Radio

Alan/Greg/Andrew/Rob,

Not sure who is currently maintaining Documentation/devices.txt.

We're needing to add support of a new type of V4L2 devices there.

Could you please ack with the following patch? If this one is ok, I intend
to send via my tree together with the patch series that implements support
for it, if you agree.

Thank you!
Mauro

Add new video4linux device named /dev/swradio for Software Defined
Radio use. V4L device minor numbers are allocated dynamically
nowadays, but there is still configuration option for old fixed style.
Add note to mention that configuration option too.
