[PATCH v2 1/1] media: tc358743: register v4l2 async device only after successful setup

[Alexander Stein]

Ensure the device has been setup correctly before registering the v4l2
async device, thus allowing userspace to access.

Change in v2:
* New approach: Register async device as last step

This superseeds the patch at [1], but has a different subject due to new
solution.
