[PATCH] Char: isicom, augment card_reset
isicom, augment card_reset - add 0xee to signatures - change long delays to sleeps - make one sleep shorter not to wait 3s - portcount == 16 is also correct Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
