Date: Fri, 30 Dec 2022 18:53:25 +0100 From: Martin Kaiser <martin@...ser.cx> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Larry Finger <Larry.Finger@...inger.net>, Phillip Potter <phil@...lpotter.co.uk>, Michael Straube <straube.linux@...il.com>, Pavel Skripkin <paskripkin@...il.com>, linux-staging@...ts.linux.dev, linux-kernel@...r.kernel.org, Martin Kaiser <martin@...ser.cx> Subject: [PATCH 3/4] staging: r8188eu: remove intermediate pframe pointer The pframe pointer in on_action_public is used only in the definition of frame_body, which points to the payload of an incoming action frame. We can use mgmt to locate the action payload and remove the pframe pointer.
