Merge tag 'char-misc-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc updates from Greg KH: "Here is the "big" char/misc driver patchset for 4.13-rc1. Lots of stuff in here, a large thunderbolt update, w1 driver header reorg, the new mux driver subsystem, google firmware driver updates, and a raft of other smaller things. Full details in the shortlog. All of these have been in linux-next for a while with the only reported issue being a merge problem with this tree and the jc-docs tree in the w1 documentation area" * tag 'char-misc-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (147 commits) misc: apds990x: Use sysfs_match_string() helper mei: drop unreachable code in mei_start mei: validate the message header only in first fragment.
