From 2d6edad4b2da1991f74e7b02053eeb4a043b887f Mon Sep 17 00:00:00 2001
From: Arend Van Spriel <arend.vanspriel@broadcom.com>
Date: Tue, 20 Feb 2018 00:14:25 +0100
Subject: [PATCH] brcmfmac: remove duplicate pointer variable from
brcmf_sdio_firmware_callback()
In brcmf_sdio_firmware_callback() two pointer variables were used
pointing to the same construct. Get rid of sdiodev variable.
