failed to open libcamhal device

I am just trying to get the test pattern out of icamerasrc but it fails with:

I think I have conflicting drivers on my system, because:

This seems to be caused by a rejected driver for /dev/media0 device. The Camera HAL is looking for a intel-ipu driver, but finds a uvcvideo driver when getting a Media Control instance.

Probably same root cause as #30. :woozy_face:

intel / icamerasrc

failed to open libcamhal device #23
