Subject: [PATCH v2] phy: renesas: rcar-gen3-usb2: disable runtime pm in case of failure
Date: Thu, 26 Nov 2020 10:44:12 +0800	[thread overview]
Message-ID: <20201126024412.4046845-1-wangli74@huawei.com> (raw)

pm_runtime_enable() will decrease power disable depth. Thus a pairing
increment is needed on the error handling path to keep it balanced.

Fixes: 5d8042e95fd4 ("phy: rcar-gen3-usb2: Add support for r8a77470")
Reported-by: Hulk Robot <hulkci@huawei.com>
Signed-off-by: Wang Li <wangli74@huawei.com>
