Subject: [PATCH v5 01/16] ufs: core: Optimize duplicate code to read extended feature
Date: Tue, 22 Nov 2022 20:10:14 -0800 [thread overview]
Message-ID: <b95fdf1a9b7d716049e286f84b94513dc30527ed.1669176158.git.quic_asutoshd@quicinc.com> (raw)
In-Reply-To: <cover.1669176158.git.quic_asutoshd@quicinc.com>
The code to parse the extended feature is duplicated twice
in the ufs core. Replace the duplicated code with a
function.
