Summary
coresight: trbe: remove cpuhp instance node before remove cpuhp state
Details

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

coresight: trbe: remove cpuhp instance node before remove cpuhp state

cpuhpstateaddinstance() and cpuhpstateremoveinstance() should be used in pairs. Or there will lead to the warn on cpuhpremovemultistate() since the cpuhpstep list is not empty.

The following is the error log with 'rmmod coresight-trbe': Error: Removing state 215 which has instances left.
