Subject: Re: [PATCH 1/2] imx-bbu-nand-fcb: do not use hardcoded devicefile
Date: Fri, 21 Feb 2025 18:47:23 +0100	[thread overview]

Hi Sasha,

sorry but I changed my workstation recently and did not restore 
send-email as on the old one. I thought the mail client geary would be 
enough but it is not.
I will send a new patch series in these days.

Best,
Stefano
