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
