This is a note to let you know that I've just added the patch titled iio: st_magn: always define ST_MAGN_TRIGGER_SET_STATE to the 4.4-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: iio-st_magn-always-define-st_magn_trigger_set_state.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 9b090a98e95c2530ef0ce474e3b6218621b8ae25 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd@xxxxxxxx> Date: Tue, 29 Mar 2016 22:27:27 +0200 Subject: iio: st_magn: always define ST_MAGN_TRIGGER_SET_STATE From: Arnd Bergmann <arnd@xxxxxxxx> commit 9b090a98e95c2530ef0ce474e3b6218621b8ae25 upstream. When CONFIG_IIO_TRIGGER is enabled but CONFIG_IIO_BUFFER is not, we get a build error in the st_magn driver: drivers/iio/magnetometer/st_magn_core.c:573:23: error: 'ST_MAGN_TRIGGER_SET_STATE' undeclared here (not in a function) .set_trigger_state = ST_MAGN_TRIGGER_SET_STATE, ^~~~~~~~~~~~~~~~~~~~~~~~~ Apparently, this ST_MAGN_TRIGGER_SET_STATE macro was meant to be set to NULL when the definition is not available because st_magn_buffer.c is not compiled, but the alternative definition was not included in the original patch. This adds it.
