[PATCH 1/1] Char: isicom, fix tty index check

[Jiri Slaby]

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.
