The fix is to make the header file more robust against inclusion from other places. While this should normally go through the i2c tree, the bug only exists in arm-soc at the moment, so it's easier to fix it there before it goes upstream. Without this patch, building s3c2410_defconfig results in: arch/arm/mach-s3c24xx/mach-osiris.c:34:0: include/linux/platform_data/i2c-s3c2410.h:37:26: warning: 'struct platform_device' declared inside parameter list [enabled by default] Signed-off-by: Arnd Bergmann Cc: linux-i2c@vger.kernel.org Cc: Wolfram Sang Cc: Ben Dooks Cc: Kukjin Kim --- diff --git a/include/linux/platform_data/i2c-s3c2410.h b/include/linux/platform_data/i2c-s3c2410.h index 51d52e767a19..2a50048c1c44 100644 --- a/include/linux/platform_data/i2c-s3c2410.h +++ b/include/linux/platform_data/i2c-s3c2410.h @@ -15,6 +15,8 @@ #define S3C_IICFLG_FILTER (1<<0) /* enable s3c2440 filter */ +struct platform_device; + /** * struct s3c2410_platform_i2c - Platform data for s3c I2C. * @bus_num: The bus number to use (if possible).
