Subject: [PATCH v2 6/9] scsi: ufs: Delete is_init_prefetch from struct ufs_hba
Date: Thu, 16 Jan 2020 22:59:11 +0100	[thread overview]
Message-ID: <20200116215914.16015-7-huobean@gmail.com> (raw)
In-Reply-To: <20200116215914.16015-1-huobean@gmail.com>

From: Bean Huo <beanhuo@micron.com>

Without variable is_init_prefetch, the current logic can guarantee
ufshcd_init_icc_levels() will execute only once, delete it now.
