Subject: [PATCH net-next v5 03/14] net: fman: Inline several functions into initialization
Date: Fri, 2 Sep 2022 17:57:25 -0400 [thread overview]
Message-ID: <20220902215737.981341-4-sean.anderson@seco.com> (raw)
In-Reply-To: <20220902215737.981341-1-sean.anderson@seco.com>
There are several small functions which were only necessary because the
initialization functions didn't have access to the mac private data. Now
that they do, just do things directly.
