NAME
       request_firmware_nowait - asynchronous version of request_firmware

SYNOPSIS
       int request_firmware_nowait(struct module * module, int uevent, const char * name, struct device * device, gfp_t gfp, void * context,
				   void (*cont) (const struct firmware *fw, void *context));

ARGUMENTS
       module
	   module requesting the firmware

       uevent
	   sends uevent to copy the firmware image if this flag is non-zero else the firmware copy must be done manually.

       name
	   name of firmware file

       device
	   device for which firmware is being loaded

       gfp
	   allocation flags

       context
	   will be passed over to cont, and fw may be NULL if firmware request fails.

       cont
	   function will be called asynchronously when the firmware request is over.

DESCRIPTION
       Asynchronous variant of request_firmware for user contexts where it is not possible to sleep for long time. It can't be called in atomic
       contexts.
