We append "Pen", "Pad", "Mouse" or "Keyboard" suffix to the appropriate

the user to know which one is which.

As I said before, this is a very welcome change. Thanks, Benjamin!
However, I'm not familiar with input_configured hook yet, so cannot give my
Reviewed-by.

+ if (suffix) {
+ len = strlen(hdev->name) + 2 + strlen(suffix);
+ name = devm_kzalloc(&hi->input->dev, len, GFP_KERNEL);
+ if (name) {
+ snprintf(name, len, "%s %s", hdev->name, suffix);
+ hi->input->name = name;
+ }

I only feel a bit uneasy about duplicating buffer size knowledge here, as I
said before, but the code is short, so it'll probably be OK.
