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.
