Subject: [PATCH v1 1/4] scsi: ufs: remove init_prefetch_data in struct ufs_hba
Date: Thu, 5 Mar 2020 12:07:01 +0800 [thread overview]
Message-ID: <20200305040704.10645-2-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20200305040704.10645-1-stanley.chu@mediatek.com>
Struct init_prefetch_data currently is used privately in
ufshcd_init_icc_levels(), thus it can be removed from struct ufs_hba.
