[PATCH] Char: isicom, fix tty index check
Since tty->index is signed and may be < 0, we should assign this to int not uint. There is already a check to ensure if it is not negative, but gcc complains with -W flag enabled and it is perfectly correct: drivers/char/isicom.c:953: warning: comparison of unsigned expression < 0 is always false Fix this issue by converting `line' variable from uint to int.
