| Subject: usb: make module xhci_hcd removable |
| |
| From: Arthur Demchenkov <spinal.by@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). |
