I didn't check either, but it shouldn't matter. If INTREN has to be set for RMI4 to work, then it must have been set even before the i2c-i801 driver was loaded. In this case, my new code is a no-op (SMBHSTCNT will be set to the value it already had, that is, INTREN is enabled at all times). -- Jean Delvare SUSE L3 Support
