If anyone has any objections, please let me know. ------------------ From: Kaustabh Chakraborty [ Upstream commit a3c2c5c937ed7562b6d120670f2743e979c05881 ] Hard matching against the WhoAmI values isn't ideal for using devices which are compatible with existing ones. Instead of raising an error, issue a warning instead, thus allowing the driver to continue probing.
