Subject: [PATCH v2 07/17] scsi: ufs: qcom: Fail ufs_qcom_power_up_sequence() when core_reset fails
Date: Fri,  8 Dec 2023 12:28:52 +0530	[thread overview]
Message-ID: <20231208065902.11006-8-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20231208065902.11006-1-manivannan.sadhasivam@linaro.org>

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.
