From 44facdc8c43a8b5172d6cbe995845c9889561aa0 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Mon, 31 Jan 2011 09:58:01 -0300 Subject: [PATCH] [media] V4L: mx3_camera: correct 'sizeimage' value reporting The 'pix->width' field may be updated in mx3_camera_set_fmt() to fulfill the IPU stride line alignment requirements. If this update takes place, the 'fmt.pix.sizeimage' field in the struct v4l2_format stucture returned by VIDIOC_S_FMT is wrong. We need to update the 'pix->sizeimage' field in the mx3_camera_set_fmt() function to fix this issue.
