Subject: [PATCH v7 13/19] staging: r8188eu: remove core/rtw_io.c
Date: Fri, 17 Sep 2021 09:18:31 +0200	[thread overview]
Message-ID: <20210917071837.10926-14-fmdefrancesco@gmail.com> (raw)
In-Reply-To: <20210917071837.10926-1-fmdefrancesco@gmail.com>

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
