Subject: Re: [PATCH v5 12/15] media: i2c: rdacm20: Embed 'serializer' field
Date: Thu, 17 Jun 2021 03:14:00 +0300 [thread overview]
Message-ID: <YMqTyFvxer0vjsKT@pendragon.ideasonboard.com> (raw)
In-Reply-To: <20210616124616.49249-13-jacopo+renesas@jmondi.org>
Hi Jacopo,
Thank you for the patch.
This should be moved before 11/15 to avoid a bisection breakage (or
11/15 should be fixed, and this patch updated accordingly).
