From: ChanWoo Lee <cw9316.lee@xxxxxxxxxxx>
Checks information about tx_lanes, but is not used.
Since the commit below is applied, tx_lanes is deprecated.
-[2/3] scsi/ufs: qcom: Remove ufs_qcom_phy_*() calls from host
-Message ID 20180904101719.18049-3-vivek.gautam@xxxxxxxxxxxxxx
As a result, link_startup_notify->POST_CHANGE action does nothing.
No need to read tx_lanes.
If it is not going to be updated, it looks like it can be removed.
