3.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Bo Shen <voice.s...@atmel.com> commit 7840487cd6298f9f931103b558290d8d98d41c49 upstream. 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 <voice.s...@atmel.com> Acked-by: Jean Delvare <kh...@linux-fr.org> Signed-off-by: Nicolas Ferre <nicolas.fe...@atmel.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagn...@jcrosoft.com> Acked-by: Ludovic Desroches <ludovic.desroc...@atmel.com> Signed-off-by: Greg Kroah-Hartman <gre...@linuxfoundation.org> --- arch/arm/mach-at91/at91rm9200_devices.c | 2 +- arch/arm/mach-at91/at91sam9260_devices.c | 2 +- arch/arm/mach-at91/at91sam9261_devices.c | 2 +- arch/arm/mach-at91/at91sam9263_devices.c | 2 +- arch/arm/mach-at91/at91sam9rl_devices.c | 2 +- 5 files changed, 5 insertions(+), 5 deletions(-) --- a/arch/arm/mach-at91/at91rm9200_devices.c +++ b/arch/arm/mach-at91/at91rm9200_devices.c @@ -463,7 +463,7 @@ static struct i2c_gpio_platform_data pda static struct platform_device at91rm9200_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; --- a/arch/arm/mach-at91/at91sam9260_devices.c +++ b/arch/arm/mach-at91/at91sam9260_devices.c @@ -471,7 +471,7 @@ static struct i2c_gpio_platform_data pda static struct platform_device at91sam9260_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; --- a/arch/arm/mach-at91/at91sam9261_devices.c +++ b/arch/arm/mach-at91/at91sam9261_devices.c @@ -285,7 +285,7 @@ static struct i2c_gpio_platform_data pda static struct platform_device at91sam9261_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; --- a/arch/arm/mach-at91/at91sam9263_devices.c +++ b/arch/arm/mach-at91/at91sam9263_devices.c @@ -542,7 +542,7 @@ static struct i2c_gpio_platform_data pda static struct platform_device at91sam9263_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; --- a/arch/arm/mach-at91/at91sam9rl_devices.c +++ b/arch/arm/mach-at91/at91sam9rl_devices.c @@ -314,7 +314,7 @@ static struct i2c_gpio_platform_data pda static struct platform_device at91sam9rl_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
