Subject: [PATCH 2/5] staging: rtl8723bs: remove sdio_writeN()
Message-ID: <7755d6f67447da830c9a2cb5d6ed3407b24e24a4.1630080164.git.hello@bryanbrattlof.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: quoted-printable
Precedence: bulk

The sdio_writeN() function is unused. We can remove it.
