i2c: Hide probe errors caused by ACPI resource conflicts
When an ACPI resource conflict is detected, error messages are already printed by ACPI. There's no point in causing the driver core to print more error messages, so return one of the error codes for which no message is printed. This fixes bug #14293: http://bugzilla.kernel.org/show_bug.cgi?id=14293 Signed-off-by: Jean Delvare <khali@linux-fr.org>
