Subject: [PATCH net-next v2 7/8] net: phy: do not print dump stack if device was removed
Date: Mon,  7 Jun 2021 10:27:26 +0200	[thread overview]
Message-ID: <20210607082727.26045-8-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210607082727.26045-1-o.rempel@pengutronix.de>

In case phy_state_machine() works on top of USB device, we can get -ENODEV
at any point. So, be less noisy if device was removed.
