Most machine files include "devices-imxXX.h" which in turn includes <mach/devices-common.h>. The latter already includes many headers that the machine files don't need to include again. These were found by: $ grep \#include arch/arm/plat-mxc/include/mach/devices-common.h > tmpfile $ git grep -l 'devices-imx' arch/arm | xargs grep -f tmpfile -F (but I kept linux/init.h, linux/kernel.h and linux/platform_device.h) LAKML-Reference: 1298912674-15153-2-git-send-email-u.kleine-koenig@pengutronix.de Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
