This is your problem. The driver expects to find a saa7115 chip at
address 0x21, but fails to. One possible reason is that the saa7115
module is failing to load - check to make sure you have one. Another
possible reason is the saa7115 is damaged. Checking in Windows would
verify this (or using i2cdetect in linux).
