The dynamic timeout may be useful for any I2C bus controller, not only
for qcom-geni. Structure i2c_adapter already has field "timeout". Isn't
it worth to move the timeout calculation to i2c-core, so that the core
updates the timeout field in i2c_adapter structure, and the controller
driver just uses this value, instead of duplicating the calculation in
every driver that will use this feature?

Also, such parameters as I2C_TIMEOUT_SAFETY_COEFFICIENT and
I2C_TIMEOUT_MIN_USEC may be configurable by user (for example, in
device tree) for more flexibility.

Best regards,
