Subject: Re: [PATCH v7 6/6] baseband/fpga_5gnr_fec: cosmetic comment changes
Date: Mon, 12 Aug 2024 11:05:41 +0200 [thread overview]
Message-ID: <522e11cf-aab1-40ae-bce2-17659bda949a@redhat.com> (raw)

Hi Hernan,
Could you please rebase and resend this patch that was missed when the
series got applied? I get some conflicts.
Thanks in advance,
Maxime
