Subject: Re: [PATCH RESEND v5 0/5] stratix10: Add framework for asynchronous
 communication with SDM

Hi Dinh,
	I hope you're doing well. It's been a while since I submitted the patch 
set, could you please take a moment to review it when you get a chance?

@Mathew Gerlach, I have addressed your comments. Please let me know if 
there’s anything else needed.

Best wishes
Mahesh Rao
