uml: driver formatting fixes
Fix a bunch of formatting violations in the drivers: return(n) -> return n whitespace fixes emacs formatting comment removal breaking if(foo) return(n) into two lines There are also a couple of errno use bugs: using errno in a printk when the failure put errno into a local variable saving errno after a printk, which can change it Signed-off-by: Jeff Dike <jdike@linux.intel.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
