Subject: [PATCH 1/2] staging: r8188eu: use subtype helpers in collect_bss_info
Date: Fri, 2 Dec 2022 10:31:58 +0100 [thread overview]
Message-ID: <20221202093159.404111-2-martin@kaiser.cx> (raw)
In-Reply-To: <20221202093159.404111-1-martin@kaiser.cx>
Use the iee80211 helper functions to check the frame subtype in
collect_bss_info. Replace the call to the driver-specific
GetFrameSubType function.
Signed-off-by: Martin Kaiser <martin@kaiser.cx>
