Subject: [PATCH v1 2/9] scsi: ufs: Introduce device parameter initialization function
Date: Mon, 16 Nov 2020 14:50:47 +0800 [thread overview]
Message-ID: <20201116065054.7658-3-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20201116065054.7658-1-stanley.chu@mediatek.com>
Nowadays many vendors initialize their device parameters in
their own vendor drivers. The initialization code is almost
the same as well as the pre-defined definitions. Introduce
a common device parameter initialization function which assign
the most common initial values. With this function, we
could remove those duplicated codes in vendor drivers.
