stm class/intel_th: Updates for 4.17
These are: * Mass conversion to GPL-2 SPDX header * Moved "hwtracing" to now its own submenu, to uncrowd the parent menu a bit * Added MAINTAINERS entry for drivers/hwtracing * Somewhat small Trace Hub fixes * Added ACPI glue layer for the Trace Hub * Added more module parameters to dummy_stm for better test coverage -----BEGIN PGP SIGNATURE----- iJkEABEIAEEWIQQSviFCoXpKPDNATbnrxfYkYwVX/wUCWrzG7yMcYWxleGFuZGVy LnNoaXNoa2luQGxpbnV4LmludGVsLmNvbQAKCRDrxfYkYwVX/0jcAQCE/maw6L5P NdT3Ck3EuDWzij9uimq3Y0UyI9F4Cd+vYgD+N8Skyiua+NqfBGB0oXNsJt2acirg O3G990RK9dX4H2c= =CuGw -----END PGP SIGNATURE----- Merge tag 'stm-intel_th-for-greg-20180329' of git://git.kernel.org/pub/scm/linux/kernel/git/ash/stm into char-misc-next Alexander writes: stm class/intel_th: Updates for 4.17 These are: * Mass conversion to GPL-2 SPDX header * Moved "hwtracing" to now its own submenu, to uncrowd the parent menu a bit * Added MAINTAINERS entry for drivers/hwtracing * Somewhat small Trace Hub fixes * Added ACPI glue layer for the Trace Hub * Added more module parameters to dummy_stm for better test coverage
