The i2c-keywest driver has a "probe" module parameter which enables bus
scanning at load time. This can be done in userspace with the i2cdetect
tool (part of the lm_sensors package) instead. What's more, i2cdetect
gives more control on the way the bus is scanned, and is safer
(i2c-keywest currently scans reserved addresses and doesn't properly
handle the famous 24RF08 corruption case.)

Thus, I would propose that this module parameter be simply dropped.
