Merge tag 'char-misc-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char / misc / IIO / other driver updates from Greg KH: "Here is the big set of char/misc/iio and other smaller driver subsystems for 6.17-rc1. It's a big set this time around, with the huge majority being in the iio subsystem with new drivers and dts files being added there. Highlights include: - IIO driver updates, additions, and changes making more code const and cleaning up some init logic - bus_type constant conversion changes - misc device test functions added - rust miscdevice minor fixup - unused function removals for some drivers - mei driver updates - mhi driver updates - interconnect driver updates - Android binder updates and test infrastructure added - small cdx driver updates - small comedi fixes - small nvmem driver updates - small pps driver updates - some acrn virt driver fixes for printk messages - other small driver updates All of these have been in linux-next with no reported issues" * tag 'char-misc-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (292 commits) binder: Use seq_buf in binder_alloc kunit tests binder: Add copyright notice to new kunit files misc: ti_fpc202: Switch to of_fwnode_handle() bus: moxtet: Use dev_fwnode() pc104: move PC104 option to drivers/Kconfig drivers: virt: acrn: Don't use %pK through printk comedi: fix race between polling and detaching interconnect: qcom: Add Milos interconnect provider driver dt-bindings: interconnect: document the RPMh Network-On-Chip Interconnect in Qualcomm Milos SoC mei: more prints with client prefix mei: bus: use cldev in prints bus: mhi: host: pci_generic: Add Telit FN990B40 modem support bus: mhi: host: Detect events pointing to unexpected TREs bus: mhi: host: pci_generic: Add Foxconn T99W696 modem bus: mhi: host: Use str_true_false() helper bus: mhi: host: pci_generic: Add support for EM929x and set MRU to 32768 for better performance. bus: mhi: host: Fix endianness of BHI vector table bus: mhi: host: pci_generic: Disable runtime PM for QDU100 bus: mhi: host: pci_generic: Fix the modem name of Foxconn T99W640 dt-bindings: interconnect: qcom,msm8998-bwmon: Allow 'nonposted-mmio' ...
