[PATCH v4 13/18] staging: r8188eu: remove core/rtw_io.c

From: Fabio M. De Francesco
Date: Mon Sep 13 2021 - 14:12:35 EST


From: Pavel Skripkin <paskripkin@xxxxxxxxx>

There are only unused functions and macros and one function which can be
open-coded.

So, remove core/rtw_io.c at all, remove core/rtw_io.c from Makefile
and open-code rtw_init_io_priv() in rtw_usb_if1_init().
