Alex Goins 68d95e759f ramdac: Check ScreenPriv != NULL in xf86ScreenSetCursor() ... Similar to change cba5a10f, xf86ScreenSetCursor() would dereference ScreenPriv without NULL checking it. If Option "SWCursor" is specified, ScreenPriv == NULL. Without this fix, it is observed that setting Option "SWCursor" "on" on the modesetting driver in a PRIME configuration will segfault the server. It is important to return success rather than failure in the instance that ScreenPriv == NULL and pCurs == NullCursor, because otherwise xf86SetCursor() can fall into infinite recursion: xf86SetCursor(pCurs) calls xf86ScreenSetCursor(pCurs), and if FALSE, calls xf86SetCursor(NullCursor). If xf86ScreenSetCursor(NullCursor) returns FALSE, it calls xf86SetCursor(NullCursor) again and this repeats forever.
