Subject: [PATCH] staging: vt6656: Use BIT_ULL() macro instead of bit shift operation
Date:   Sat,  7 Mar 2020 11:49:29 +0100
Message-Id: <20200307104929.7710-1-oscar.carter@gmx.com>
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Replace the bit left shift operation with the BIT_ULL() macro and remove
the unnecessary "and" operation against the bit_nr variable.
