Subject: [PATCH 1/4] staging:r8188eu: replace get_(d|s)a with ieee80211_get_(D|S)A
Date:   Sun, 14 Mar 2021 12:02:44 +0300
Message-Id: <20210314090247.21181-2-insafonov@gmail.com>
In-Reply-To: <20210314090247.21181-1-insafonov@gmail.com>
References: <20210314090247.21181-1-insafonov@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

get_da()/get_sa() duplicate native ieee80211_get_(D|S)A functions.
Remove get_(d|s)a, use ieee80211_get_(D|S)A instead.
