From 24105ebc0567f2864999a8176be681c62fe31350 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Wed, 23 Mar 2011 05:41:28 -0300 Subject: [media] soc-camera: fix a recent multi-camera breakage on sh-mobile With the introduction of CSI2 support on sh-mobile, the host driver switched to using v4l2_device_call_until_err() with grp_id == 0 to call subdev operations on the sensor and the CSI2 subdev. However, this has broken multi-client set ups like the one on migor, because that way all operations get called on both clients. To fix this add a grp_id and set it to the client private context.
