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

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.
Well, the hook is called just before we present the input to the user
space. So the input node is already set and its corresponding report
has been parsed (or the whole descriptor has been parsed if
QUIRK_MULTI_INPUT is not set).
Thanks for the explanation, but basing my Reviewed-by on your explanation
wouldn't be right, even though this seems simple :) I'll read up the kernel
code tomorrow.

+ 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.
I am not quite sure what you mean with "duplicating buffer size
knowledge"...
Argh, nevermind, just sleepy me, sorry. You fixed it, thanks, looks fine :)
