Merge tag 'char-misc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH: "Here's the "big" char and misc driver update for 4.9-rc1. Lots of little things here, all over the driver tree for subsystems that flow through me. Nothing major that I can discern, full details are in the shortlog. All have been in the linux-next tree with no reported issues" * tag 'char-misc-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (144 commits) drivers/misc/hpilo: Changes to support new security states in iLO5 FW at25: fix debug and error messaging misc/genwqe: ensure zero initialization vme: fake: remove unexpected unlock in fake_master_set() vme: fake: mark symbols static where possible spmi: pmic-arb: Return an error code if sanity check fails Drivers: hv: get rid of id in struct vmbus_channel Drivers: hv: make VMBus bus ids persistent mcb: Add a dma_device to mcb_device mcb: Enable PCI bus mastering by default mei: stop the stall timer worker if not needed clk: probe common clock drivers earlier vme: fake: fix build for 64-bit dma_addr_t ttyprintk: Neaten and simplify printing mei: me: add kaby point device ids coresight: tmc: mark symbols static where possible coresight: perf: deal with error condition properly Drivers: hv: hv_util: Avoid dynamic allocation in time synch fpga manager: Add hardware dependency to Zynq driver Drivers: hv: utils: Support TimeSync version 4.0 protocol samples. ...
