Fixed version (ground truth):
void grantUriPermissionLocked(int callingUid,String targetPkg,Uri uri,int modeFlags,UriPermissionOwner owner){
  int targetUid=checkGrantUriPermissionLocked(callingUid,targetPkg,uri,modeFlags);
  if (targetUid < 0) {
    return;
  }
  grantUriPermissionUncheckedLocked(targetUid,targetPkg,uri,modeFlags,owner);
}
