Subject: [PATCH 1/1] PCI: mediatek: Remove redundant error printing in mtk_pcie_subsys_powerup()
Date: Tue, 11 May 2021 20:24:53 +0800 [thread overview]
Message-ID: <20210511122453.6052-1-thunder.leizhen@huawei.com> (raw)
When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.
Therefore, remove the error printing here to simplify code and reduce the
binary size.
