Subject: toshiba_acpi: Fix hotkeys registration on some toshiba models

From: Azael Avalos <[email protected]>

commit 53147b6cabee5e8d1997b5682fcc0c3b72ddf9c2 upstream.

Commit a2b3471b5b13 ("toshiba_acpi: Use the Hotkey Event Type function for keymap choosing") changed the *setup_keyboard function to query for the Hotkey Event Type to help choose the correct keymap, but turns out that here are certain Toshiba models out there not implementing this feature, and thus, failing to continue the input device registration and leaving such laptops without hotkey support.

This patch changes such check, and instead of returning an error if the Hotkey Event Type is not present, we simply inform userspace about it, changing the message printed from err to notice, making the function responsible for registering the input device to continue.

This issue was found on a Toshiba Portege Z30-B, but there might be some other models out there affected by this regression as well.
