Looking at the naming patterns in the surrounding code:
```c++
void handleKernelEntryPointAttr(Decl *D, const ParsedAttr &AL);
void CheckSYCLExternalFunctionDecl(FunctionDecl *FD);
```
Should we rename the first parameter of `CheckDeviceUseOfDecl` from its current name to `ND` to maintain consistency? It appears the codebase follows a pattern of using single/double letter parameter names (like `D`, `FD`) for declaration-type parameters in similar functions.
