Merge tag 'char-misc-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-miscHEADmaster
Pull Char/Misc/IIO/others driver updates from Greg KH: "Here is the big set of char/misc/android/iio and other small driver subsystem patches for 7.4-rc1. Loads of stuff in here, larger than normal. Highlights include: - removal of the C binder code, the rust version is stable and will be used going forward in a few billion devices. Great job by those developers - loads and loads of IIO driver updates and feature additions - speakup driver fixes and updates - mhi driver updates - mei driver updates - xillybus driver fixes - comedi driver fixes - lots of coresight driver updates - Interconnect driver updates - nvmem driver updates and fixes - slimbus driver updates and fixes - spmi driver updates and fixes - lots of tiny misc and char driver fixes based on people scanning for things All of these have been in linux-next for a while with no reported issues, other than a merge conflict with one of the rust tree files, which should be simple to resolve" * tag 'char-misc-7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (446 commits) rust_binder: wake epoll on self-work queued to poll thread rust_binder: avoid overflow in get_node_debug_info() MAINTAINERS: Add Abel as SPMI co-maintainer spmi: mtk-pmif: Fix clock reference leak in mtk_spmi_bus_probe() iio: adc: qcom-spmi-iadc: Remove regmap R/W wrapper functions iio: adc: qcom-spmi-iadc: Migrate to devm_spmi_subdevice_alloc_and_add() misc: qcom-coincell: Migrate to devm_spmi_subdevice_alloc_and_add() phy: qualcomm: eusb2-repeater: Migrate to devm_spmi_subdevice_alloc_and_add() power: reset: qcom-pon: Migrate to devm_spmi_subdevice_alloc_and_add() nvmem: qcom-spmi-sdam: Migrate to devm_spmi_subdevice_alloc_and_add() spmi: Add helper to get a parent SPMI device spmi: Implement spmi_subdevice_alloc_and_add() and devm variant spmi: Remove unneeded goto in spmi_device_add() error path spmi: Print error status with %pe format spmi: Remove redundant dev_name() print in spmi_device_add() spmi: Fix potential use-after-free by grabbing of_node reference spmi: mtk-pmif: Add workaround for FSM lockup/error in read operation MAINTAINERS: Add Qualcomm SPMI controller entry spmi: pmic-arb: return 0 in spmi_pmic_arb_register_buses() on success comedi: addi_apci_3xxx: fix subdevice count underallocation ...
