394 | * The silead.c touchscreen driver does not support runtime suspend, so | |
395 | * the GPIO can only be changed underneath us during a system suspend. | |
396 | * This resume() function runs from a pm complete() callback, and thus | |
397 | * is guaranteed to run after the touchscreen driver/ACPI-subsys has | |
398 | * brought the touchscreen back up again (and thus changed the GPIO). | |
399 | * | |
400 | * So to work around this we pass GPIOD_FLAGS_BIT_NONEXCLUSIVE when | |
401 | * requesting the GPIO and we set its value here to undo any changes | |
402 | * done by the touchscreen's broken _PS0 ACPI method. | |
