Subject: [PATCH AUTOSEL 5.10 58/65] usb: dwc3: omap: fix "unbalanced disables for smps10_out1" on omap5evm
Date: Fri, 1 Apr 2022 10:41:59 -0400 [thread overview]
Message-ID: <20220401144206.1953700-58-sashal@kernel.org> (raw)
In-Reply-To: <20220401144206.1953700-1-sashal@kernel.org>
From: "H. Nikolaus Schaller" <hns@goldelico.com>
[ Upstream commit ac01df343e5a6c6bcead2ed421af1fde30f73e7e ]
Usually, the vbus_regulator (smps10 on omap5evm) boots up disabled.
Hence calling regulator_disable() indirectly through dwc3_omap_set_mailbox()
during probe leads to:

Fix this unnecessary warning by checking if the regulator is enabled.
