- ensure pKernelFifo->ppChidMgr[i]->pChanGrpTree is successfully
allocated in function kfifoChidMgrConstruct_IMPL(), otherwise
it may cause invalid memory access when calling mapFine(). - only invoke mapDestroy() when pKernelFifo->ppChidMgr[i]->pChanGrpTree
is not NULL in function kfifoChidMgrDestruct_IMPL(), otherwise
it may cause invalid memory access. - ensure pChidMgr is valid in function kfifoGetChannelGroup_IMPL().
1) ensure pKernelFifo->ppChidMgr[i]->pChanGrpTree is successfully
allocated in function kfifoChidMgrConstruct_IMPL(), otherwise
it may cause invalid memory access when calling mapFine().
2) only invoke mapDestroy() when pKernelFifo->ppChidMgr[i]->pChanGrpTree
is not NULL in function kfifoChidMgrDestruct_IMPL(), otherwise
it may cause invalid memory access.
3) ensure pChidMgr is valid in function kfifoGetChannelGroup_IMPL().
