From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel Mack Date: Tue, 19 Jun 2018 09:56:15 +0000 Subject: [PATCH] video: fbdev: pxafb: zero allocated memory for video modes Message-Id: <20180619095615.14680-1-daniel@zonque.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-fbdev@vger.kernel.org When parsing the video modes from DT properties, make sure to zero out memory befor using it. This is important because not all fields in the mode struct are explicitly initialized, even though they are used later on.
