[BUG] not compiling with SDSORT_DYNAMIC_RAM enabled

[Hasi123]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

If you enable SDSORT_DYNAMIC_RAM with the latest Marlin, I get this error on compilation:

C:\Users\David\Documents\GitHub\Marlin\Marlin\src\sd\cardreader.cpp: In static member function 'static void CardReader::presort()': C:\Users\David\Documents\GitHub\Marlin\Marlin\src\sd\cardreader.cpp:1062:72: error: incompatible types in assignment of 'char*' to 'char [66]' #define SET_SORTNAME(I) (sortnames[I] = strdup(longest_filename())) ^ C:\Users\David\Documents\GitHub\Marlin\Marlin\src\sd\cardreader.cpp:1155:13: note: in expansion of macro 'SET_SORTNAME' SET_SORTNAME(i); ^~~~~~~~~~~~ exit status 1 Error compiling for board Sanguino.

Obviously you have to disable SDCARD_RATHERRECENTFIRST and enable SDCARD_SORT_ALPHA and SDSORT_USES_RAM...

Expected behavior

No compiler errors.

Actual behavior

Compiler error.

Steps to Reproduce
