Char/Misc driver fixes for 5.10-rc4

Browse Source 
Here are some small char/misc/whatever driver fixes for 5.10-rc4.
 
 Nothing huge, lots of small fixes for reported issues:
 	- habanalabs driver fixes
 	- speakup driver fixes
 	- uio driver fixes
 	- virtio driver fix
 	- other tiny driver fixes
 Full details are in the shortlog.
 
 All of these have been in linux-next for a full week with no reported
 issues.
