From 289011207d999b2e4085150d2aa30d547ad9b800 Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Fri, 16 May 2008 11:10:30 +0200 Subject: [PATCH] Move definition of container_of() to common.h AVR32 and AT91SAM9 both have their own identical definitions of container_of() taken from the Linux kernel. Move it to common.h so that all architectures can use it. container_of() is already used by some drivers, and will be used extensively by the new and improved SPI API.
