Arnd Bergmann 2b5a6d7714 nds32: fix access_ok() checks in get/put_user ... commit 8926d88ced46700bf6117ceaf391480b943ea9f4 upstream. The get_user()/put_user() functions are meant to check for access_ok(), while the __get_user()/__put_user() functions don't. This broke in 4.19 for nds32, when it gained an extraneous check in __get_user(), but lost the check it needs in __put_user().
