Merge tag 'char-misc-4.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver fixes from Greg KH: "Here are a handful of char/misc driver fixes for 4.16-rc3. There are some binder driver fixes to resolve reported issues in stress testing the recent binder changes, some extcon driver fixes, and a few mei driver fixes and new device ids. All of these, with the exception of the mei driver id additions, have been in linux-next for a while. I forgot to push out the mei driver id additions to kernel.org until today, but all build tests pass with them enabled" * tag 'char-misc-4.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: mei: me: add cannon point device ids for 4th device mei: me: add cannon point device ids mei: set device client to the disconnected state upon suspend. ANDROID: binder: synchronize_rcu() when using POLLFREE. binder: replace "%p" with "%pK" ANDROID: binder: remove WARN() for redundant txn error binder: check for binder_thread allocation failure in binder_poll() extcon: int3496: process id-pin first so that we start with the right status Revert "extcon: axp288: Redo charger type detection a couple of seconds after probe()" extcon: axp288: Constify the axp288_pwr_up_down_info array
