From b04c846ceaad42f9e37f3626c7e8f457603863f0 Mon Sep 17 00:00:00 2001 From: Arthur Demchenkov Date: Tue, 19 May 2015 16:30:50 +0300 Subject: [PATCH] usb: make module xhci_hcd removable 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).
