Bug ID: 48545
           Summary: SDL GameControllerAddMapping registry keys do not work
           Product: Wine
           Version: 5.0
          Hardware: x86
                OS: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: hid
          Assignee: [e-mail]
          Reporter: [e-mail]

The registry entries to add SDL controller mappings do not work
(HKLM/CurrentControlSet/Services/WineBus/Map)

I've discovered the enumeration of the subkeys fails with ERROR_ACCESS_DENIED

If I change the RegOpenKeyExW call (line 1039 of bus_sdl.c) to use KEY_READ
instead of KEY_ENUMERATE_SUB_KEYS the enumeration succeeds and the controller
mappings are passed to SDL.

The registry keys were created with the stock wine regedit program.

I can provide a diff if really required, but I feel like this might be an issue
that needs solving somewhere else (perhaps the default permissions on registry
key creation need tweaking?)
