Sami Mujawar 31eaefd4df ArmPkg: Fix uninitialised variable in ArmMmuStandaloneMmLib ... The following patches added support for StandaloneMM using FF-A: 9da5ee116a ArmPkg: Allow FF-A calls to set memory region's attributes 0e43e02b9b ArmPkg: Allow FF-A calls to get memory region's attributes However, in the error handling logic for the Get/Set Memory attributes, the CLANG compiler reports that a status variable could be used without initialisation. This issue is a false positive and is not seen with GCC. The Get/Set Memory attributes operation is atomic and therefore an FFA_INTERRUPT or FFA_SUCCESS response is not expected in response to FFA_MSG_SEND_DIRECT_REQ. So the remaining cases that could occur are: - the target sends FFA_MSG_SEND_DIRECT_RESP with a success or failure code. or - FFA_MSG_SEND_DIRECT_REQ transmission failure. Therefore, - reorder the error handling conditions such that it prevents the uninitialised variable issue being flagged by CLANG. - move the repetitive code to a static helper function and add documentation at the appropriate places. - fix error handling in functions that invoke GetMemoryPermissions().
