[PATCH] char/isicom: More whitespaces and coding style
Wrap all the code to 80 chars on a line. `}\nelse' changed to `} else'. Clean whitespaces in header file. Signed-off-by: Jiri Slaby <xslaby@fi.muni.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
