Subject: [PATCH v2 02/17] ufs: core: Optimize duplicate code to read extended feature
Date: Wed, 5 Oct 2022 18:06:01 -0700	[thread overview]
Message-ID: <ac0b25115456457339af5ed64ce8456ec66c6c3f.1665017636.git.quic_asutoshd@quicinc.com> (raw)
In-Reply-To: <cover.1665017636.git.quic_asutoshd@quicinc.com>

The code to parse the extended feature is duplicated more then 2
times in the ufs core. Replace the duplicated code with the
function.
