From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sachin Kamat Date: Tue, 18 Sep 2012 11:50:00 +0000 Subject: [PATCH 2/2] video: exynos_mipi_dsi: Fix potential NULL pointer dereference Message-Id: <1347968280-22343-2-git-send-email-sachin.kamat@linaro.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-fbdev@vger.kernel.org The error message printed when dsim is NULL references its member. This will cause NULL pointer derefernce error. Hence change dev_err to pr_err to avoid it.
