Merge tag 'char-misc-5.13-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 various smaller driver subsystem updates for
5.13-rc1.
Major bits in here are:
- habanalabs driver updates
- hwtracing driver updates
- interconnect driver updates
- mhi driver updates
- extcon driver updates
- fpga driver updates
- new binder features added
- nvmem driver updates
- phy driver updates
- soundwire driver updates
- smaller misc and char driver fixes and updates.
- bluetooth driver bugfix that maintainer wanted to go through this
tree.
All of these have been in linux-next with no reported issues"
