In the Linux kernel, the following vulnerability has been resolved:

ACPI: EC: Fix oops when removing custom query handlers

When removing custom query handlers, the handler might still
be used inside the EC query workqueue, causing a kernel oops
if the module holding the callback function was already unloaded.

Fix this by flushing the EC query workqueue when removing
custom query handlers.

Tested on a Acer Travelmate 4002WLMi
