gpiolib: Update documentation of struct acpi_gpio_info
It seems the code had been changed, but description left untouched. Update description of the struct acpi_gpio_info and relative comments accordingly. Fixes: commit 52044723cd27 ("ACPI / gpio: Add irq_type when a GPIO is used as an interrupt") Cc: Christophe RICARD <christophe.ricard@gmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
