Subject: [PATCH 1/1] drm/mediatek: Remove redundant error printing in mtk_dsi_probe()
Date: Tue, 11 May 2021 18:00:01 +0800	[thread overview]
Message-ID: <20210511100001.5047-1-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.
