From 3ae5eaec1d2d9c0cf53745352e7d4b152810ba24 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 9 Nov 2005 22:32:44 +0000 Subject: [DRIVER MODEL] Convert platform drivers to use struct platform_driver This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers.
