[PATCH 5/6] [media] gsc-m2m: add device name sufix to bus_info capatiliby field
From: Javier Martinez Canillas
Date: Thu Jun 16 2016 - 17:41:43 EST
The driver doesn't set the device in the struct v4l2_capability bus_info
field so v4l2-compliance reports the following error for VIDIOC_QUERYCAP:
Required ioctls:
fail: v4l2-compliance.cpp(537): missing bus_info prefix ('platform')
test VIDIOC_QUERYCAP: FAIL
This patch fixes this by filling also the device besides the bus.
