In a std::unique_ptr<T[]>, the '.get()' type is T[]* instead of T[]

[Tal]

According to https://en.cppreference.com/w/cpp/memory/unique_ptr, the pointer type of std::unique_ptr<T[]> is T* and not T[]*. However, I get the following error in cppcheck 2.14.0 (on linux):

 portability (arithOperationsOnVoidPointer): 'buf.get()' is of type 'void *'. When using void pointers in calculations, the behaviour is undefined. Arithmetic operations on 'void *' is a GNU C extension, which defines the 'sizeof(void)' to be 1

For the following type of code:

 std::unique_ptr<char[]> buf = std::make_unique<char[]>(dataSize);
return buf.get() + size;

Even though that buf.get() is of type char*.
