Subject: [PATCH] mt76: Use the correct hweight8() function again
Date:   Sun, 17 Mar 2019 11:32:28 +0900
Message-Id: <1552789948-31564-1-git-send-email-yamada.masahiro@socionext.com>

Precedence: bulk

Commit d0ff23c1107e ("mt76: Use the correct hweight8() function")
fixed the wrong use of __sw_hweight8().

Just a week later, commit c8846e101502 ("mt76: add driver for MT7603E
and MT7628/7688") was applid, introducing __sw_hweight8() again.

Fixes: c8846e101502 ("mt76: add driver for MT7603E and MT7628/7688")
