This reverts commit 532223c8ac57605a10e46dc0ab23dcf01c9acb43.
As reported in [0], hid-logitech-hidpp now binds on all bluetooth mice,
but there are corner cases where hid-logitech-hidpp just gives up on
the mouse. This leads the end user with a dead mouse.
Given that we are at -rc8, we are definitively too late to find a proper
fix. We already identified 2 issues less than 24 hours after the bug
report. One in that ->match() was never designed to be used anywhere else
than in hid-generic, and the other that hid-logitech-hidpp has corner
cases where it gives up on devices it is not supposed to.
So we have no choice but postpone this patch to the next kernel release.
