Char / Misc driver fixes for 5.9-rc5
Here are a number of small driver fixes for 5.9-rc5
Included in here are:
- habanalabs driver fixes
- interconnect driver fixes
- soundwire driver fixes
- dyndbg fixes for reported issues, and then reverts to fix it
all up to a sane state.
- phy driver fixes
Full details of these are in the shortlog.
All of these have been in linux-next for a while with no reported
issues.
