Subject: [PATCH v4 5/6] PCI: uniphier: Add error message when failed to get phy
Date:   Fri,  5 Jun 2020 18:44:35 +0900
Message-Id: <1591350276-15816-6-git-send-email-hayashi.kunihiko@socionext.com>
In-Reply-To: <1591350276-15816-1-git-send-email-hayashi.kunihiko@socionext.com>
References: <1591350276-15816-1-git-send-email-hayashi.kunihiko@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
