Char/Misc fixes for 4.15-rc3

Browse source 
Here are some small misc driver fixes for 4.15-rc3 to resolve reported
 issues.  Specifically these are:
 	- binder fix for a memory leak
 	- vpd driver fixes for a number of reported problems
 	- hyperv driver fix for memory accesses where it shouldn't be.
 
 All of these have been in linux-next for a while.  There's also one more
 MAINTAINERS file update that came in today to get the Android
 developer's emails correct, which is also in this pull request, that was
 not in linux-next, but should not be an issue.
