Subject: [PATCH 2/2] staging: r8188eu: use subtype helper in rtw_check_bcn_info
Date:   Fri,  2 Dec 2022 10:31:59 +0100
Message-Id: <20221202093159.404111-3-martin@kaiser.cx>
In-Reply-To: <20221202093159.404111-1-martin@kaiser.cx>

Use ieee80211_is_beacon to check the frame subtype in rtw_check_bcn_info.
Replace the call to the driver-specific GetFrameSubType function.
