Message-ID: <20120915153323.GA1391@polaris.bitmath.org>
Date: Sat, 15 Sep 2012 17:33:23 +0200
From: "Henrik Rydberg" <rydberg@...omail.se>
To: Dmitry Torokhov <dmitry.torokhov@...il.com>
Cc: Jiri Kosina <jkosina@...e.cz>, linux-input@...r.kernel.org,
linux-kernel@...r.kernel.org
Subject: Input and HID updates for 3.7, version 4
Ok, here is version 4 of the patchset. Rather than sending out all the
patches again, the diff to linux-next is given below, and the
refreshed tree can be pulled from
git://github.com/rydberg/linux.git maybe
All Dmitry's comments are addressed. Changes in short:
* Also move 'slot' to input_mt
* Oops fix amended
* New patch to allow driver pressure handling
* Keep the synaptics specials in bcm5974
Needless to say, I want to move this tree to linux-next soonish, so if
there are more comments coming, I would appreciate a heads-up.
Thanks,
Henrik
