I don't like that. I've found the code and taken a quick look at it. I'm still not sure I understand your point. The semantics for any device attempting to register with an I2C ID table should be unchanged. The only intended difference would be for drivers which do not wish to supply one due to the fact that they have other means of matching, namely DT and ACPI. Would you mind telling me what I have changed that affects drivers registering via Sysfs? -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
