Date: Wed, 30 May 2012 13:13:09 +0200 Message-Id: <1338376389-32256-1-git-send-email-javier.martin@vista-silicon.com> X-Mailer: git-send-email 1.7.0.4 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1900 Lines: 55 Some GPIOs in Visstrim M10 are used without being registered. This leads to USB and video malfunctions. This patch registers those GPIOs to solve the issue.
