This is a note to let you know that I've just added the patch titled Input: tsc200x - report proper input_dev name to the 4.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: input-tsc200x-report-proper-input_dev-name.patch and it can be found in the queue-4.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From e9003c9cfaa17d26991688268b04244adb67ee2b Mon Sep 17 00:00:00 2001 From: Michael Welling <mwelling@xxxxxxxx> Date: Wed, 20 Jul 2016 10:02:07 -0700 Subject: Input: tsc200x - report proper input_dev name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Michael Welling <mwelling@xxxxxxxx> commit e9003c9cfaa17d26991688268b04244adb67ee2b upstream. Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.
