Pull char/misc updates from Greg KH: "Here is the big char/misc driver update for 4.6-rc1. The majority of the patches here is hwtracing and some new mic drivers, but there's a lot of other driver updates as well. Full details in the shortlog. All have been in linux-next for a while with no reported issues" * tag 'char-misc-4.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (238 commits) goldfish: Fix build error of missing ioremap on UM nvmem: mediatek: Fix later provider initialization nvmem: imx-ocotp: Fix return value of imx_ocotp_read nvmem: Fix dependencies for !HAS_IOMEM archs char: genrtc: replace blacklist with whitelist drivers/hwtracing: make coresight-etm-perf.c explicitly non-modular drivers: char: mem: fix IS_ERROR_VALUE usage char: xillybus: Fix internal data structure initialization pch_phub: return -ENODATA if ROM can't be mapped Drivers: hv: vmbus: Support kexec on ws2012 r2 and above Drivers: hv: vmbus: Support handling messages on multiple CPUs Drivers: hv: utils: Remove util transport handler from list if registration fails Drivers: hv: util: Pass the channel information during the init call Drivers: hv: vmbus: avoid unneeded compiler optimizations in vmbus_wait_for_unload() Drivers: hv: vmbus: remove code duplication in message handling Drivers: hv: vmbus: avoid wait_for_completion() on crash Drivers: hv: vmbus: don't loose HVMSG_TIMER_EXPIRED messages misc: at24: replace memory_accessor with nvmem_device_read eeprom: 93xx46: extend driver to plug into the NVMEM framework eeprom: at25: extend driver to plug into the NVMEM framework ...
