This is a note to let you know that I have just added a patch titled i2c: mux: gpio: use gpio_set_value_cansleep() to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.14. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From f3a9eaddaa89a84a1f59154665ce0551bcbea350 Mon Sep 17 00:00:00 2001 From: Ionut Nicu <ioan.nicu.ext@nsn.com> Date: Fri, 11 Oct 2013 14:17:10 +0200 Subject: i2c: mux: gpio: use gpio_set_value_cansleep() commit 250ad590d6f12d93f4d85be305b0a598d609232e upstream. Some gpio chips may have get/set operations that can sleep. gpio_set_value() only works for chips which do not sleep, for the others we will get a kernel warning. Using gpio_set_value_cansleep() will work for both chips that do sleep and those who don't.
