Subject: [PATCH v2 1/1] irqchip: Remove redundant error printing
Date: Tue, 11 May 2021 20:54:28 +0800	[thread overview]
Message-ID: <20210511125428.6108-2-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210511125428.6108-1-thunder.leizhen@huawei.com>

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.
