Pull modules updates from Jessica Yu:
 "Summary of modules changes for the 5.5 merge window:

   - Refactor include/linux/export.h and remove code duplication between
     EXPORT_SYMBOL and EXPORT_SYMBOL_NS to make it more readable.

     The most notable change is that no namespace is represented by an
     empty string "" rather than NULL.

   - Fix a module load/unload race where waiter(s) trying to load the
     same module weren't being woken up when a module finally goes away"
