Subject: [PATCH] staging: r8188eu: remove HW_VAR_SLOT_TIME from SetHwReg8188EU()
Date:   Mon,  6 Jun 2022 08:40:55 +0200
Message-Id: <20220606064055.12565-1-straube.linux@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

In order to get rid of the function SetHwReg8188EU() remove the
HW_VAR_SLOT_TIME case from that function and move the functionality
into a static function in rtw_wlan_util.c.
