gpio: ep93xx: Fix port F hwirq numbers in handler
[ Upstream commit 0f04cdbdb210000a97c773b28b598fa8ac3aafa4 ] Fix wrong translation of irq numbers in port F handler, as ep93xx hwirqs increased by 1, we should simply decrease them by 1 in translation. Fixes: 482c27273f52 ("ARM: ep93xx: renumber interrupts") Signed-off-by: Nikita Shubin <nikita.shubin@maquefel.me> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
