You're checking that it's 0x80, then using
sparse_keymap_entry_from_scancode() to effectively check whether it's
0x80, so this is redundant. But I suspect that this is actually wrong -
0x80 is often used as a generic notification event, with a separate
method for looking up the actual keycode. Do you have some ASL
describing the device?
Also, could you add a description of what the device does to the commit
so it shows up nicely in the changelog?
