Please make sure to inspect and if appropriate modify the coccinelle output for the 'best' coding style, for whatever definition of 'best' you might use, before submitting automatically produced patches. > diff --git a/drivers/i2c/busses/i2c-jz4780.c b/drivers/i2c/busses/i2c-jz4780.c [] > @@ -133,10 +133,10 @@ static const char * const jz4780_i2c_abrt_src[] = { > > #define JZ4780_I2C_ENB_I2C BIT(0) > > -#define JZ4780_I2CSHCNT_ADJUST(n) (((n) - 8) < 6 ? 6 : ((n) - 8)) > -#define JZ4780_I2CSLCNT_ADJUST(n) (((n) - 1) < 8 ? 8 : ((n) - 1)) > -#define JZ4780_I2CFHCNT_ADJUST(n) (((n) - 8) < 6 ? 6 : ((n) - 8)) > -#define JZ4780_I2CFLCNT_ADJUST(n) (((n) - 1) < 8 ? 8 : ((n) - 1)) > +#define JZ4780_I2CSHCNT_ADJUST(n) (max(6, (n) - 8)) > +#define JZ4780_I2CSLCNT_ADJUST(n) (max(8, (n) - 1)) > +#define JZ4780_I2CFHCNT_ADJUST(n) (max(6, (n) - 8)) > +#define JZ4780_I2CFLCNT_ADJUST(n) (max(8, (n) - 1)) For instance: the parentheses are unnecessary and could be removed like the BIT macro above. > -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Thanks for pointing it out. I will resend the patch.

Replace ternary operators with macro 'max' as it is shorter and thus increases code readability. Macro max returns the maximum of the two compared values.
