gpio: ep93xx: fix test for end of loop
The problem is that if port == ARRAY_SIZE() and "gc == &epg->gc[port]" then that should be treated as invalid. Fixes: fd935fc421e7 ("gpio: ep93xx: Do not pingpong irq numbers") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
