gpio: aspeed: fix compile testing warning
Gcc cannot always see that BUG_ON(1) is guaranteed to not return, so we get a warning message in some configurations: drivers/gpio/gpio-aspeed.c: In function 'bank_reg': drivers/gpio/gpio-aspeed.c:244:1: error: control reaches end of non-void function [-Werror=return-type] Using a plain BUG() is easier here and avoids the problem. Fixes: 44ddf559d579 ("gpio: aspeed: Rework register type accessors") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
