Technical description

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.
