Subject: [PATCH][resubmit] xpad.c: Add rumble support for original xbox controller
Date: Wed, 20 Jan 2010 01:04:06 +0100 [thread overview]
Message-ID: <20100120010406.54a11bc6@rechenknecht2k7> (raw)
Hi,
Seems like this got lost somehow, I also did some minor coding style
changes to better comply with the kernel standards.
Since this is a patch against Linux 2.6.33-rc4, I've also added the fix
from [1].

This patch adds rumble support for xbox 1 compatible controllers.
