Char/Misc driver fixes for 5.9-rc3

Browse Source 
Here are some small char and misc and other driver subsystem fixes for
 5.9-rc3.
 
 The majority of these are tiny habanalabs driver fixes, but also in here
 are:
 	- speakup build fixes now that it is out of staging and got
 	  exposed to more build systems all of a sudden
 	- mei driver fix
 
 All of these have been in linux-next for a while with no reported
 issues.
