[PATCH v2 1/4] i2c: i801: remove printout on handled timeouts
Posted by Wolfram Sang 1 year, 9 months ago
I2C and SMBus timeouts are not something the user needs to be informed
about on controller level. The client driver may know if that really is
a problem and give more detailed information to the user. The controller
should just pass this information upwards. Remove the printout and turn
the SMBus-specific termination message to debug.
