By making use of the i2c_driver.detect() mechanism like in my patch, we can actually reduce the number of lines in the driver. Looking forward to your comments on my other solution proposal! / Martin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
