Merge tag 'char-misc-5.15-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 set of char/misc driver changes for 5.15-rc1. Lots of different driver subsystems are being updated in here, notably: - mhi subsystem update - fpga subsystem update - coresight/hwtracing subsystem update - interconnect subsystem update - nvmem subsystem update - parport drivers update - phy subsystem update - soundwire subsystem update and there are some other char/misc drivers being updated as well: - binder driver additions - new misc drivers - lkdtm driver updates - mei driver updates - sram driver updates - other minor driver updates. Note, there are no habanalabs driver updates in this pull request, that will probably come later before -rc1 is out in a different request. All of these have been in linux-next for a while with no reported problems" * tag 'char-misc-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (169 commits) Revert "bus: mhi: Add inbound buffers allocation flag" misc/pvpanic: fix set driver data VMCI: fix NULL pointer dereference when unmapping queue pair char: mware: fix returnvar.cocci warnings parport: remove non-zero check on count soundwire: cadence: do not extend reset delay soundwire: intel: conditionally exit clock stop mode on system suspend soundwire: intel: skip suspend/resume/wake when link was not started soundwire: intel: fix potential race condition during power down phy: qcom-qmp: Add support for SM6115 UFS phy dt-bindings: phy: qcom,qmp: Add SM6115 UFS PHY bindings phy: qmp: Provide unique clock names for DP clocks lkdtm: remove IDE_CORE_CP crashpoint lkdtm: replace SCSI_DISPATCH_CMD with SCSI_QUEUE_RQ coresight: Replace deprecated CPU-hotplug functions.
