Subject: [PATCH v5 13/19] staging: r8188eu: remove core/rtw_io.c
Date:   Wed, 15 Sep 2021 14:41:43 +0200

From: Pavel Skripkin <paskripkin@gmail.com>

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

So, removed core/rtw_io.c at all, removed core/rtw_io.c from Makefile
and open-coded rtw_init_io_priv
