Merge tag 'char-misc-5.15-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull habanalabs updates from Greg KH: "Here is another round of misc driver patches for 5.15-rc1. In here is only updates for the Habanalabs driver. This request is late because the previously-objected-to dma-buf patches are all removed and some fixes that you and others found are now included in here as well. All of these have been in linux-next for well over a week with no reports of problems, and they are all self-contained to only this one driver. Full details are in the shortlog" * tag 'char-misc-5.15-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (61 commits) habanalabs/gaudi: hwmon default card name habanalabs: add support for f/w reset habanalabs/gaudi: block ICACHE_BASE_ADDERESS_HIGH in TPC habanalabs: cannot sleep while holding spinlock habanalabs: never copy_from_user inside spinlock habanalabs: remove unnecessary device status check habanalabs: disable IRQ in user interrupts spinlock habanalabs: add "in device creation" status habanalabs/gaudi: invalidate PMMU mem cache on init habanalabs/gaudi: size should be printed in decimal habanalabs/gaudi: define DC POWER for secured PMC habanalabs/gaudi: unmask out of bounds SLM access interrupt habanalabs: add userptr_lookup node in debugfs habanalabs/gaudi: fetch TPC/MME ECC errors from F/W habanalabs: modify multi-CS to wait on stream masters habanalabs/gaudi: add monitored SOBs to state dump habanalabs/gaudi: restore user registers when context opens habanalabs/gaudi: increase boot fit timeout habanalabs: update to latest firmware headers habanalabs/gaudi: minimize number of register reads ...

+Description: Gets the state dump occurring on a CS timeout or failure.
+ State dump is used for debug and is created each time in case of
+ a problem in a CS execution, before reset.
+ Reading from the node returns the newest state dump available.
+ Writing an integer X discards X state dumps, so that the
+ next read would return X+1-st newest state dump.
