From b1cbab05d9adbd8d6d7afc822b809c5d47c46f94 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 18 Apr 2013 18:35:27 -0300 Subject: [media] V4L2: add a common V4L2 subdevice platform data type This struct shall be used by subdevice drivers to pass per-subdevice data, e.g. power supplies, to generic V4L2 methods, at the same time allowing optional host-specific extensions via the host_priv pointer. To avoid having to pass two pointers to those methods, add a pointer to this new struct to struct v4l2_subdev.
