From 00d3dcdd96646be6059cc21f2efa94c4edc1eda5 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 9 Nov 2005 17:23:39 +0000 Subject: [DRIVER MODEL] Add platform_driver Introduce struct platform_driver. This allows the platform device driver methods to be passed a platform_device structure instead of instead of a plain device structure, and therefore requiring casting in every platform driver. We introduce this in such a way that any existing platform drivers registered directly via driver_register continue to work as before, thereby allowing a gradual conversion to the new platform_driver methods.
