Subject: hp_accel: fix race in device removal
From: Oliver Neukum <oneukum@xxxxxxx>
The work queue has to be flushed after the device has been made
inaccessible. The patch closes a window during which a work queue might
remain active after the device is removed and would then lead to ACPI
calls with undefined behavior.
