Merge tag 'char-misc-4.21-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 set of char and misc driver patches for 4.21-rc1. Lots of different types of driver things in here, as this tree seems to be the "collection of various driver subsystems not big enough to have their own git tree" lately. Anyway, some highlights of the changes in here: - binderfs: is it a rule that all driver subsystems will eventually grow to have their own filesystem? Binder now has one to handle the use of it in containerized systems. This was discussed at the Plumbers conference a few months ago and knocked into mergable shape very fast by Christian Brauner. Who also has signed up to be another binder maintainer, showing a distinct lack of good judgement :) - binder updates and fixes - mei driver updates - fpga driver updates and additions - thunderbolt driver updates - soundwire driver updates - extcon driver updates - nvmem driver updates - hyper-v driver updates - coresight driver updates - pvpanic driver additions and reworking for more device support - lp driver updates. Yes really, it's _finally_ moved to the proper parallal port driver model, something I never thought I would see happen. Good stuff. - other tiny driver updates and fixes. All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (116 commits) MAINTAINERS: add another Android binder maintainer intel_th: msu: Fix an off-by-one in attribute store stm class: Add a reference to the SyS-T document stm class: Fix a module refcount leak in policy creation error path char: lp: use new parport device model char: lp: properly count the lp devices char: lp: use first unused lp number while registering char: lp: detach the device when parallel port is removed char: lp: introduce list to save port number bus: qcom: remove duplicated include from qcom-ebi2.c VMCI: Use memdup_user() rather than duplicating its implementation char/rtc: Use of_node_name_eq for node name comparisons misc: mic: fix a DMA pool free failure ptp: fix an IS_ERR() vs NULL check genwqe: Fix size check binder: implement binderfs binder: fix use-after-free due to ksys_close() during fdget() bus: fsl-mc: remove duplicated include files bus: fsl-mc: explicitly define the fsl_mc_command endianness misc: ti-st: make array read_ver_cmd static, shrinks object size ...
