Subject: [patch] rio500 devfs support
Date: Tue, 19 Jun 2001 17:52:24 -0500 [thread overview]
Message-ID: <20010619175224.A1137@glitch.snoozer.net> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 292 bytes --]
The attached diff adds devfs support to the rio500 driver, so that
/dev/usb/rio500 gets created automagically. It was generated against
2.4.5, but probably applies fine against any recent kernel. Comments
are welcome (but be gentle, this is my first attempt at a kernel
patch :-).
Cheers!
