Subject: [PATCH v4 3/6] scsi: ufs: Group UFS WB related flags to struct ufs_dev_info
From: Bean Huo <beanhuo@...ron.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
