From: Hugo Villeneuve <hvilleneuve@xxxxxxxxxxxx> Hello, this patch series brings a few fixes in the probing of the max310x driver. Patches 1 to 3 could be merged if deemed necessary and to facilitate stable kernel backporting. Note that I do not have access to a board with an actual max310x IC on it, but I have tested it by using i2c-stub to simulate the four ports on a virtual max14830 device. Thank you.
