[PATCH 1/2] include: linux: siox: more for declaring siox drivers

From: Enrico Weigelt, metux IT consult
Date: Mon Jun 17 2019 - 14:26:30 EST


From: Enrico Weigelt <info@xxxxxxxxx>

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.
