If card is using downloadable firmware (like Agere 9.x), firmware has to be reloaded during resume. It is not possible to use request_firmware for that, because tasks are still frozen, so request_firmware will just timeout and fail. So cache firmware image in memory for later reuse in ->resume method. Signed-off-by: Andrey Borzenkov <arvidjaar@mail.ru> Signed-off-by: John W. Linville <linville@tuxdriver.com>
