4.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arthur Demchenkov <spinal...@gmail.com>
commit b04c846ceaad42f9e37f3626c7e8f457603863f0 upstream.
Fixed regression. After commit 29e409f0f761 ("xhci: Allow xHCI drivers to
be built as separate modules") the module xhci_hcd became non-removable.
That behaviour is not expected and there're no notes about it in commit
message. The module should be removable as it blocks PM suspend/resume
functions (Debian Bug#666406).
