Merge tag 'char-misc-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc and other driver updates from Greg KH: "Here is the big set of char/misc and other driver subsystem changes for 6.8-rc1. Other than lots of binder driver changes (as you can see by the merge conflicts) included in here are: - lots of iio driver updates and additions - spmi driver updates - eeprom driver updates - firmware driver updates - ocxl driver updates - mhi driver updates - w1 driver updates - nvmem driver updates - coresight driver updates - platform driver remove callback api changes - tags.sh script updates - bus_type constant marking cleanups - lots of other small driver updates All of these have been in linux-next for a while with no reported issues" * tag 'char-misc-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (341 commits) android: removed duplicate linux/errno uio: Fix use-after-free in uio_open drivers: soc: xilinx: add check for platform firmware: xilinx: Export function to use in other module scripts/tags.sh: remove find_sources scripts/tags.sh: use -n to test archinclude scripts/tags.sh: add local annotation scripts/tags.sh: use more portable -path instead of -wholename scripts/tags.sh: Update comment (addition of gtags) firmware: zynqmp: Convert to platform remove callback returning void firmware: turris-mox-rwtm: Convert to platform remove callback returning void firmware: stratix10-svc: Convert to platform remove callback returning void firmware: stratix10-rsu: Convert to platform remove callback returning void firmware: raspberrypi: Convert to platform remove callback returning void firmware: qemu_fw_cfg: Convert to platform remove callback returning void firmware: mtk-adsp-ipc: Convert to platform remove callback returning void firmware: imx-dsp: Convert to platform remove callback returning void firmware: coreboot_table: Convert to platform remove callback returning void firmware: arm_scpi: Convert to platform remove callback returning void firmware: arm_scmi: Convert to platform remove callback returning void ...
