[clang-tidy][false-positive] misc-const-correctness warns non-const pointer parameter despite passing function into function pointer #236012
Description
https://godbolt.org/z/fG16E4Pev
misc-const-correctness warns that pointee of a pointer parameter from a function should be const, yet the very same function is passed into a function pointer that has a non-const pointer parameter.
We don't always control the function pointer signature. And in cases we don't control the signature, following the suggestion will cause the code to FTBFS.
<source>:4:14: warning: pointee of variable 'p' of type 'T *const' can be declared 'const' [misc-const-correctness]
4 | void destroy(T* const p) { delete p; }
| ^
| const
