Description
In the Linux kernel, the following vulnerability has been resolved:
net/mana: Null service_wq on setup error to prevent double destroy
In mana_gd_setup() error path, set gc->service_wq to NULL after
destroy_workqueue() to match the cleanup in mana_gd_cleanup().
This prevents a use-after-free if the workqueue pointer is checked
after a failed setup.
