From: Jean Delvare <[email protected]> Subject: i2c-viapro: Don't log nacks
Transactions not acked can happen every now and then, in particular during device detection, and various transaction types can be used for this purpose. So stop logging this event, except when debugging is enabled. This is what other similar drivers (e.g. i2c-i801 or i2c-piix4) do.
