This is a note to let you know that I have just added a patch titled i2c: mux: pca954x: Use __i2c_transfer because of quirks to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.y-ckt4. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 68231e4eca12e2ee43c645d17a124b5110eb9a72 Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin <alexander.sverdlin@nokia.com> Date: Fri, 12 Jun 2015 14:41:00 +0200 Subject: i2c: mux: pca954x: Use __i2c_transfer because of quirks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 0a8237ae319ab5988d40a7a9b33d68846aae34b4 upstream. pca9541 and pca954x are calling master_xfer() of the parent adapter directly thus bypassing the quirks checks of the adapter. Use __i2c_transfer() instead.
