int request_firmware_nowait
(struct module * module, int uevent, const char * name, struct device * device, void * context, void (*cont)
(const struct firmware *fw, void *context));
module requesting the firmware
sends uevent to copy the firmware image if this flag is non-zero else the firmware copy must be done manually.
name of firmware file
device for which firmware is being loaded
will be passed over to cont, and fw may be NULL if firmware request fails.
function will be called asynchronously when the firmware request is over.
Asynchronous variant of request_firmware for contexts where it is not possible to sleep.
