Subject: [PATCH v5 02/19] staging: r8188eu: remove the helpers of rtw_read8()
Date: Wed, 15 Sep 2021 14:41:32 +0200	[thread overview]
Message-ID: <20210915124149.27543-3-fmdefrancesco@gmail.com> (raw)
In-Reply-To: <20210915124149.27543-1-fmdefrancesco@gmail.com>

From: Pavel Skripkin <paskripkin@gmail.com>

Remove the unnecessary _rtw_read8() and usb_read8() and embed their
code into the caller (i.e., rtw_read8()).

_rtw_read8() is a mere redefinition of rtw_read8() and it is unneeded.
usb_read8() was the only functions assigned to (*_usb_read8) pointer,
so we can simply remove it and make a direct call.

This patch is in preparation for the _io_ops structure removal.
