Subject: [PATCH v2 1/2] include: linux: siox: more for declaring siox drivers
Date: Tue, 18 Jun 2019 12:40:26 +0200	[thread overview]
Message-ID: <1560854427-27537-2-git-send-email-info@metux.net> (raw)
In-Reply-To: <1560854427-27537-1-git-send-email-info@metux.net>

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.
