For data structure types "struct vm", its name is identical with variable name in the same scope. This is a MISRA C violation. Naming convention rule:If the data structure type is used by multi modules, its corresponding logic resource is exposed to external components (such as SOS, UOS), and its name meaning is simplistic (such as vcpu, vm), its name needs prefix "acrn_". The following udpates are made: struct vm *vm-->struct acrn_vm *vm Tracked-On: #861 Signed-off-by: Xiangyang Wu <xiangyang.wu@linux.intel.com>
