In armada_37xx_gpio_direction_output(), the 'ret' variable might store the negative error codes returned by regmap_update_bits(), and in armada_37xx_edge_both_irq_swap_pol(), the 'ret' variable directly stores -1, so the type of the 'ret' variable needs to be changed to int in both cases. No effect on runtime. Signed-off-by: Qianfeng Rong <rongqianfeng@vivo.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
