Subject: [PATCH AUTOSEL 5.16 098/109] usb: dwc3: omap: fix "unbalanced disables for smps10_out1" on omap5evm
Date: Fri,  1 Apr 2022 10:32:45 -0400	[thread overview]
Message-ID: <20220401143256.1950537-98-sashal@kernel.org> (raw)
In-Reply-To: <20220401143256.1950537-1-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.
