Summary
In the Linux kernel, the following vulnerability has been resolved:
coresight: trbe: remove cpuhp instance node before remove cpuhp state
cpuhp_state_add_instance() and cpuhp_state_remove_instance() should
be used in pairs. Or there will lead to the warn on
cpuhp_remove_multi_state() since the cpuhp_step list is not empty.
The following is the error log with 'rmmod coresight-trbe':
Error: Removing state 215 which has instances left.
