I do however think this series is good in itself and would like to see it merged. As any fix for this problem would be done on top of the patches in this series.

Hi Bjorn, I have a series that removes couple of these function calls - ufs_qcom_phy_set_tx_lane_enable(), and ufs_qcom_phy_save_controller_version() from ufs-qcom, and make phy-qcom-ufs-qmp-20nm as broken. I can post it out if that sounds okay. Best regards Vivek [snip]
