This uses a standard HUT code for the F12 key with the 6 square boxes on it,
which gets mapped to KEY_FILE by the kernel. Change the mapping done of
identical laptop key done by thinkpad_acpi to also send KEY_FILE for
consistency.

When CONFIG_FUJITSU_LAPTOP_DEBUG is disabled and W=1, the
fujitsu-laptop driver builds with the following warnings:

xgene_enet_get_ring_size() returns a negative value in case of an error,
but its only caller in xgene_enet_create_desc_ring() currently uses the
return value directly as u32. Instead, check for a negative value first and
error out in case. Also move the call to xgene_enet_get_ring_size() before
devm_kzalloc() so we don't need to free anything in the error path.

This fixes the following issue reported by the Coverity Scanner:

** CID 1231336:  Improper use of negative value  (NEGATIVE_RETURNS)

Xbox One controllers require an initialization message to start sending

controller does not have LEDs like the Xbox 360 controller, so that
functionality is not implemented. The format of messages controlling rumble
is currently undocumented, so rumble support is not yet implemented.

Note that Xbox One controller advertises three interfaces with the same
