From 213cf90b9ad07d40c1e7aa5781907695107fe188 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 26 Mar 2012 08:54:26 -0300 Subject: [PATCH] [media] omap3isp: preview: Skip brightness and contrast in configuration ioctl Brightness and contrast are handled through V4L2 controls. Their configuration bit in the preview engine update attributes table is set to -1 to reflect that. However, the VIDIOC_OMAP3ISP_PRV_CFG ioctl handler doesn't handle -1 correctly as a configuration bit value, and erroneously considers that the parameter has been selected for update by the ioctl caller. Fix this.
