Before pulling this patch into mainline, I ran the checkpatch
--git test as requested by Tom. This reveals some mostly minor
issues:

WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?
#51: 
new file mode 100644

WARNING: line over 80 characters

total: 1 errors, 4 warnings, 2 checks, 914 lines checked

Could you please check and fix most of these issues (BIT macro, missing
blank line, code indentation and space@start of line)?

Thanks,
Stefan
