Do not quite like it... I'd rather asynchronous request give out a
firmware status pointer that could be used later on.

pcu->fw_st = request_firmware_async(IMS_PCU_FIRMWARE_NAME,
pcu,
ims_pcu_process_async_firmware);
if (IS_ERR(pcu->fw_st))
return PTR_ERR(pcu->fw_st);

....

fw_loading_wait(pcu->fw_st);


In the remoteproc case (patch 6) this would clean up the code, rather
than replacing the completion API 1 to 1. I like it!

IIRC most drivers do it the same way. So request_firmware_async() indeed would be good thing to have. Let me try that.

Thanks for the excellent feedback.

cheers,
