To: LKML; +Cc: Ben Fennema, Jan Kara, Christoph Hellwig, Marcin Slusarz
fix coding style errors found by checkpatch:
- assignments in if conditions
- braces {} around single statement blocks
- no spaces after commas
- printks without KERN_*
- lines longer than 80 characters
before: total: 50 errors, 207 warnings, 1835 lines checked
after: total: 0 errors, 164 warnings, 1872 lines checked
all 164 warnings left are lines longer than 80 characters;
this file has too much indentation with really long expressions
to break all those lines now
