Subject: [PATCH] staging: comedi: proc.c Fixed warning and brace code style issue [kernel: linux-next:	next-20130607]

checkpatch provided a warning on line 38. It recommended seq_puts instead of seq_printf.
Since the return value of printf is ignored, I decided to switch to the seq_puts
function since it is just regular character output.
source:: http://lwn.net/Articles/22355/

I also added braces on a for loop, since loops should be in braces.
