Merge tag 'char-misc-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver updates from Greg KH: "Here is the big char/misc driver update for 4.14-rc1. Lots of different stuff in here, it's been an active development cycle for some reason. Highlights are: - updated binder driver, this brings binder up to date with what shipped in the Android O release, plus some more changes that happened since then that are in the Android development trees. - coresight updates and fixes - mux driver file renames to be a bit "nicer" - intel_th driver updates - normal set of hyper-v updates and changes - small fpga subsystem and driver updates - lots of const code changes all over the driver trees - extcon driver updates - fmc driver subsystem upadates - w1 subsystem minor reworks and new features and drivers added - spmi driver updates Plus a smattering of other minor driver updates and fixes. All of these have been in linux-next with no reported issues for a while" * tag 'char-misc-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (244 commits) ANDROID: binder: don't queue async transactions to thread.
