Merge tag 'char-misc-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char/misc driver fixes from Greg KH:
 "Here are some small char and misc driver fixes for 4.13-rc2. All fix
  reported problems with 4.13-rc1 or older kernels (like the binder
  fixes). Full details in the shortlog.

  All have been in linux-next with no reported issues"

* tag 'char-misc-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc:
  w1: omap-hdq: fix error return code in omap_hdq_probe()
  regmap: regmap-w1: Fix build troubles
  w1: Fix slave count on 1-Wire bus (resend)
  mux: mux-core: unregister mux_class in mux_exit()
  mux: remove the Kconfig question for the subsystem
  nvmem: rockchip-efuse: amend compatible rk322x-efuse to rk3228-efuse
  drivers/fsi: fix fsi_slave_mode prototype
  fsi: core: register with postcore_initcall
  thunderbolt: Correct access permissions for active NVM contents
  vmbus: re-enable channel tasklet
  spmi: pmic-arb: Always allocate ppid_to_apid table
  MAINTAINERS: Add entry for SPMI subsystem
  spmi: Include OF based modalias in device uevent
  binder: Use wake up hint for synchronous transactions.
  binder: use group leader instead of open thread
  Revert "android: binder: Sanity check at binder ioctl"

help
Multiplexer controller subsystem. Multiplexers are used in a
variety of settings, and this subsystem abstracts their use
so that the rest of the kernel sees a common interface. When
multiple parallel multiplexers are controlled by one single
multiplexer controller, this subsystem also coordinates the
multiplexer accesses.
To compile the subsystem as a module, choose M here: the module will
be called mux-core.
