Subject: [PATCH v2 1/2] phy: qcom-qmp: fix pipe-clock imbalance on power-on failure
Date: Mon,  2 May 2022 15:31:29 +0200	[thread overview]
Message-ID: <20220502133130.4125-2-johan+linaro@kernel.org> (raw)
In-Reply-To: <20220502133130.4125-1-johan+linaro@kernel.org>

Make sure to disable the pipe clock also if ufs-reset deassertion fails
during power on.

Note that the ufs-reset is asserted in qcom_qmp_phy_com_exit().
