I agree that Wolfram was too generous with his clean-ups this time. Wolfram, you should only be removing the calls to i2c_set_clientdata(x, NULL), not changing the logic of the code. Furthermore, lirc_zilog is currently undergoing heavy changes, I'd rather let Andy and Jarod work on that staging driver, and clean up what needs to be later. -- Jean Delvare -- 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
