If there is no device on the address, the table will be empty. Currently with the i2c-eg20t driver, the table is not visible because the error messages destroy the table. Error message: pch_i2c_getack return -71 This patch prevent the driver to print the messages to syslog. The pch_i2c_wait_for_check_xfer function is the only one who is calling pch_i2c_getack, so we can delete the function and add the read to pch_i2c_wait_for_check_xfer. If no ACK is received, the Message will be printed as a dbg message. Fixed print message to be a one liner so we can grep for the error message. Tested on Intel Atom E6xx and Eg20t Chipset.
