This is a note to let you know that I've just added the patch titled hwmon: (gpio-fan) Prevent overflow problem when writing large limits to the 3.16-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: hwmon-gpio-fan-prevent-overflow-problem-when-writing-large-limits.patch and it can be found in the queue-3.16 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 2565fb05d1e9fc0831f7b1c083bcfcb1cba1f020 Mon Sep 17 00:00:00 2001 From: Axel Lin <axel.lin@xxxxxxxxxx> Date: Sat, 2 Aug 2014 13:36:38 +0800 Subject: hwmon: (gpio-fan) Prevent overflow problem when writing large limits From: Axel Lin <axel.lin@xxxxxxxxxx> commit 2565fb05d1e9fc0831f7b1c083bcfcb1cba1f020 upstream. On platforms with sizeof(int) < sizeof(unsigned long), writing a rpm value larger than MAXINT will result in unpredictable limit values written to the chip. Avoid auto-conversion from unsigned long to int to fix the problem.
