Merge tag 'char-misc-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc drivers updates from Greg KH: "Here is the "big" set of char/misc and other driver subsystems for 6.4-rc1. It's pretty big, but due to the removal of pcmcia drivers, almost breaks even for number of lines added vs. removed, a nice change. Included in here are: - removal of unused PCMCIA drivers (finally!) - Interconnect driver updates and additions - Lots of IIO driver updates and additions - MHI driver updates - Coresight driver updates - NVMEM driver updates, which required some OF updates - W1 driver updates and a new maintainer to manage the subsystem - FPGA driver updates - New driver subsystem, CDX, for AMD systems - lots of other small driver updates and additions All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (196 commits) mcb-lpc: Reallocate memory region to avoid memory overlapping mcb-pci: Reallocate memory region to avoid memory overlapping mcb: Return actual parsed size when reading chameleon table kernel/configs: Drop Android config fragments virt: acrn: Replace obsolete memalign() with posix_memalign() spmi: Add a check for remove callback when removing a SPMI driver spmi: fix W=1 kernel-doc warnings spmi: mtk-pmif: Drop of_match_ptr for ID table spmi: pmic-arb: Convert to platform remove callback returning void spmi: mtk-pmif: Convert to platform remove callback returning void spmi: hisi-spmi-controller: Convert to platform remove callback returning void w1: gpio: remove unnecessary ENOMEM messages w1: omap-hdq: remove unnecessary ENOMEM messages w1: omap-hdq: add SPDX tag w1: omap-hdq: allow compile testing w1: matrox: remove unnecessary ENOMEM messages w1: matrox: use inline over __inline__ w1: matrox: switch from asm to linux header w1: ds2482: do not use assignment in if condition w1: ds2482: drop unnecessary header ...
