This is in response to https://lore.kernel.org/all/Zh0qKeI-YPDE-NVT@xxxxxxxxxxxxxxxxxxxx/ Instead of extending the existing smbus probe to include a retry loop, this patch takes the same approach as i2c_hid_set_power() by retrying on EREMOTEIO. This maintains the "silent" error in case no device is present without having to send any dummy commands. Tested with a disconnected touchpad on a Dell XPS 13. I left out the particular sleep. If one is needed, it should also be added to i2c_hid_set_power() which is where we'd wake the device after resuming from suspend. Lukasz and Radoslaw, can you please test if this still does the trick?
