	 * The Huawei device tree sets cd-gpios = <&msmgpio 38 GPIO_ACTIVE_HIGH>.
	 * However, gpio38 does not change its state when inserting/removing the
	 * SD card, it's just low all the time. The Huawei kernel seems to use
	 * polling for SD card detection instead.
	 *
	 * However, looking closer at the GPIO debug output it turns out that
	 * gpio56 switches its state when inserting/removing the SD card.
	 * It behaves just like gpio38 normally does. Usually GPIO56 is used as
	 * "UIM2_PRESENT", i.e. to check if a second SIM card is inserted.
	 * Maybe Huawei decided to replace the second SIM card slot with the
	 * SD card slot and forgot to re-route to gpio38.
