Subject: [PATCH v1] PCI: controller: Remove duplicate error message
Date:   Tue, 26 May 2020 23:09:54 +0800
Message-Id: <20200526150954.4729-1-zhengdejin5@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

It will print an error message by itself when
devm_pci_remap_cfg_resource() goes wrong. so remove the duplicate
error message.
