Add a new video device test that opens user specified Video Device and
calls video ioctls in a loop once every 10 seconds.
This test is intended for testing device removal and driver unbind while
an ioctl is active. Clean device removal and driver unbind is expected
without any use-after-free and panics.

ioctl is called.

selftests: add a new test for Media Controller API2016-02-25T16:47:02+00:00Shuah Khanshuahkh@osg.samsung.com2016-02-13T00:43:31+00:00urn:sha1:9d22f6e14e249713108c8adcc8705c39303f0628
This test opens user specified Media Device and calls
MEDIA_IOC_DEVICE_INFO ioctl in a loop once every 10
seconds. This test is for detecting errors in device
removal path.
Usage:
sudo ./media_device_test -d /dev/mediaX
While test is running, remove the device and
ensure there are no use after free errors and
other Oops in the dmesg. Enable KaSan kernel
config option for use-after-free error detection.
