Merge tag 'char-misc-5.16-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 and misc and other tiny driver subsystem updates for 5.16-rc1. Loads of things in here, all of which have been in linux-next for a while with no reported problems (except for one called out below.) Included are: - habanana labs driver updates, including dma_buf usage, reviewed and acked by the dma_buf maintainers - iio driver update (going through this tree not staging as they really do not belong going through that tree anymore) - counter driver updates - hwmon driver updates that the counter drivers needed, acked by the hwmon maintainer - xillybus driver updates - binder driver updates - extcon driver updates - dma_buf module namespaces added (will cause a build error in arm64 for allmodconfig, but that change is on its way through the drm tree) - lkdtm driver updates - pvpanic driver updates - phy driver updates - virt acrn and nitr_enclaves driver updates - smaller char and misc driver updates" * tag 'char-misc-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (386 commits) comedi: dt9812: fix DMA buffers on stack comedi: ni_usb6501: fix NULL-deref in command paths arm64: errata: Enable TRBE workaround for write to out-of-range address arm64: errata: Enable workaround for TRBE overwrite in FILL mode coresight: trbe: Work around write to out of range coresight: trbe: Make sure we have enough space coresight: trbe: Add a helper to determine the minimum buffer size coresight: trbe: Workaround TRBE errata overwrite in FILL mode coresight: trbe: Add infrastructure for Errata handling coresight: trbe: Allow driver to choose a different alignment coresight: trbe: Decouple buffer base from the hardware base coresight: trbe: Add a helper to pad a given buffer area coresight: trbe: Add a helper to calculate the trace generated coresight: trbe: Defer the probe on offline CPUs coresight: trbe: Fix incorrect access of the sink specific data coresight: etm4x: Add ETM PID for Kryo-5XX coresight: trbe: Prohibit trace before disabling TRBE coresight: trbe: End the AUX handle on truncation coresight: trbe: Do not truncate buffer on IRQ coresight: trbe: Fix handling of spurious interrupts ...
