[PATCH 2/7] Revert "HID: logitech: fix a used uninitialized GCC warning"

[Benjamin Tissoires <benjamin.tissoires@redhat.com>]

This reverts commit 5fe2ccbef9d7aecf5c4402c753444f1a12096cfd.

It turns out the current API is not that compatible with
some Microsoft mice, so better start again from scratch.
