Subject: [PATCH 1/2] siox: add helper macro to simplify driver registration
Date:   Mon, 24 Jun 2019 07:40:33 +0200
Message-Id: <1561354834-22617-2-git-send-email-info@metux.net>
In-Reply-To: <1561354834-22617-1-git-send-email-info@metux.net>
References: <1561354834-22617-1-git-send-email-info@metux.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Enrico Weigelt <info@metux.net>

Add more helper macros for trivial driver init cases, similar to the
already existing module_platform_driver() or module_i2c_driver().

This helps to reduce driver init boilerplate.
