From 302090a66b85bb82023b07a715f9c9a347be2ac8 Mon Sep 17 00:00:00 2001 From: Bo Shen Date: Mon, 15 Oct 2012 17:30:28 +0800 Subject: ARM: at91/i2c: change id to let i2c-at91 work The i2c core driver will turn the platform device ID to busnum When using platfrom device ID as -1, it means dynamically assigned the busnum. When writing code, we need to make sure the busnum, and call i2c_register_board_info(int busnum, ...) to register device if using -1, we do not know the value of busnum In order to solve this issue, set the platform device ID as a fix number Here using 0 to match the busnum used in i2c_regsiter_board_info() Signed-off-by: Bo Shen Signed-off-by: Nicolas Ferre Acked-by: Jean-Christophe PLAGNIOL-VILLARD Acked-by: Ludovic Desroches --- arch/arm/mach-at91/at91rm9200_devices.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm/mach-at91/at91rm9200_devices.c') diff --git a/arch/arm/mach-at91/at91rm9200_devices.c b/arch/arm/mach-at91/at91rm9200_devices.c index 7cd80533ec5d..1e122bcd7845 100644 --- a/arch/arm/mach-at91/at91rm9200_devices.c +++ b/arch/arm/mach-at91/at91rm9200_devices.c @@ -512,7 +512,7 @@ static struct resource twi_resources[] = { static struct platform_device at91rm9200_twi_device = { .name = "i2c-at91rm9200", - .id = -1, + .id = 0, .resource = twi_resources, .num_resources = ARRAY_SIZE(twi_resources), }; -- cgit v1.2.3
