Merge tag 'char-misc-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc updates from Greg KH: "Here is the big set of char/misc driver patches for 4.17-rc1. There are a lot of little things in here, nothing huge, but all important to the different hardware types involved: - thunderbolt driver updates - parport updates (people still care...) - nvmem driver updates - mei updates (as always) - hwtracing driver updates - hyperv driver updates - extcon driver updates - ... and a handful of even smaller driver subsystem and individual driver updates All of these have been in linux-next with no reported issues" * tag 'char-misc-4.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (149 commits) hwtracing: Add HW tracing support menu intel_th: Add ACPI glue layer intel_th: Allow forcing host mode through drvdata intel_th: Pick up irq number from resources intel_th: Don't touch switch routing in host mode intel_th: Use correct method of finding hub intel_th: Add SPDX GPL-2.0 header to replace GPLv2 boilerplate stm class: Make dummy's master/channel ranges configurable stm class: Add SPDX GPL-2.0 header to replace GPLv2 boilerplate MAINTAINERS: Bestow upon myself the care for drivers/hwtracing hv: add SPDX license id to Kconfig hv: add SPDX license to trace Drivers: hv: vmbus: do not mark HV_PCIE as perf_device Drivers: hv: vmbus: respect what we get from hv_get_synint_state() /dev/mem: Avoid overwriting "err" in read_mem() eeprom: at24: use SPDX identifier instead of GPL boiler-plate eeprom: at24: simplify the i2c functionality checking eeprom: at24: fix a line break eeprom: at24: tweak newlines eeprom: at24: refactor at24_probe() ...
