Subject: [PATCH] usb: i.MX: improve regulator handling
Date: Tue, 20 Oct 2020 13:15:37 +0200 [thread overview]
Message-ID: <20201020111537.29328-1-u.kleine-koenig@pengutronix.de> (raw)
Instead of just ignoring errors related to regulator getting error out.
In case there is no regulator in the device tree, regulator_get() returns
the dummy regulator and not an error code, so the change is right for
this situation, too.
