Subject: [PATCH v4 3/6] scsi: ufs: Group UFS WB related flags to struct ufs_dev_info
Date: Fri, 11 Dec 2020 15:00:32 +0100	[thread overview]
Message-ID: <20201211140035.20016-4-huobean@gmail.com> (raw)
In-Reply-To: <20201211140035.20016-1-huobean@gmail.com>

From: Bean Huo <beanhuo@micron.com>

UFS device-related flags should be grouped in ufs_dev_info. Take
wb_enabled and wb_buf_flush_enabled out from the struct ufs_hba,
group them to struct ufs_dev_info, and align the names of the structure
members vertically
