Sumanth Korikkar 439077c39d s390/diag324: Preserve -EBUSY return code ... When diag324 reports -EBUSY, the error code is overwritten by the result of copy_to_user() and put_user(). As a result, the ioctl may incorrectly return success instead of -EBUSY. Preserve the original diag324 return code and only return -EFAULT when copying data to userspace fails.
