Merge tag 'char-misc-4.18-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 and misc driver patches for 4.18-rc1. It's not a lot of stuff here, but there are some highlights: - coreboot driver updates - soundwire driver updates - android binder updates - fpga big sync, mostly documentation - lots of minor driver updates All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (81 commits) vmw_balloon: fixing double free when batching mode is off MAINTAINERS: Add driver-api/fpga path fpga: clarify that unregister functions also free documentation: fpga: move fpga-region.txt to driver-api documentation: fpga: add bridge document to driver-api documentation: fpga: move fpga-mgr.txt to driver-api Documentation: fpga: move fpga overview to driver-api fpga: region: kernel-doc fixes fpga: bridge: kernel-doc fixes fpga: mgr: kernel-doc fixes fpga: use SPDX fpga: region: change api, add fpga_region_create/free fpga: bridge: change api, don't use drvdata fpga: manager: change api, don't use drvdata fpga: region: don't use drvdata in common fpga code Drivers: hv: vmbus: Removed an unnecessary cast from void * ver_linux: Drop redundant calls to system() to test if file is readable ver_linux: Move stderr redirection from function parameter to function body misc: IBM Virtual Management Channel Driver (VMC) rpmsg: Correct support for MODULE_DEVICE_TABLE() ...
