Can you address this in the next spin of the series (I don't think its in the following patches that I glanced through).

Even though core_reset is optional, a failure during assert/deassert should be considered fatal, if core_reset is available. So fail ufs_qcom_power_up_sequence() if an error happens during reset and also get rid of the redundant warning as the ufs_qcom_host_reset() function itself prints error messages.
