From 3acbb0142d48713a8f65cde678a54f419801c189 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen <lars@metafoo.de> Date: Wed, 16 Nov 2011 10:13:37 +0100 Subject: [PATCH] SPI: Add helper macro for spi_driver boilerplate This patch introduces the module_spi_driver macro which is a convenience macro for SPI driver modules similar to module_platform_driver. It is intended to be used by drivers which init/exit section does nothing but register/unregister the SPI driver. By using this macro it is possible to eliminate a few lines of boilerplate code per SPI driver.
