Mgerge remote-tracking branch 'torvalds/master' into perf/core
To sync headers, for instance, in this case tools/perf was ahead of upstream till Linus merged tip/perf/core to get the PERF_RECORD_TEXT_POKE changes: Warning: Kernel ABI header at 'tools/include/uapi/linux/perf_event.h' differs from latest version at 'include/uapi/linux/perf_event.h' diff -u tools/include/uapi/linux/perf_event.h include/uapi/linux/perf_event.h Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

+title: CZ.NIC's Turris Omnia LEDs driver
+
+maintainers:
+ - Marek BehĂșn <marek.behun@nic.cz>
+
+description:
+ This module adds support for the RGB LEDs found on the front panel of the
+ Turris Omnia router. There are 12 RGB LEDs that are controlled by a
+ microcontroller that communicates via the I2C bus. Each LED is described
+ as a subnode of this I2C device.
