Subject: [PATCH 5.4 097/203] scsi: ufs: Give an unique ID to each ufs-bsg

From: Can Guo <cang@...eaurora.org>

commit 8c850a0296004409e7bcb9464712fb2807da656a upstream.

Considering there can be multiple UFS hosts in SoC, give each ufs-bsg an
unique ID by appending the scsi host number to its device name.
