Subject: [PATCH 5/5] PCI: uniphier: Add error message when failed to get phy
Date: Fri, 15 May 2020 13:48:25 +0900 [thread overview]
Message-ID: <1589518105-18368-6-git-send-email-hayashi.kunihiko@socionext.com> (raw)
In-Reply-To: <1589518105-18368-1-git-send-email-hayashi.kunihiko@socionext.com>
Even if phy driver doesn't probe, the error message can't be
distinguished from other errors. This displays error message
caused by the phy driver explicitly.
