Thanks for the overnight fix. This update fixes the issue on my
Skylake XPS13 test device (blind testing since I don't understand what
the code does).
Tested-by: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>
I need to take this back, this set of changes (initial+fix) causes an
error with our HDMI support

Removing your changes restores the functionality
Adding some traces I can see that the the platform name we use doesn't
seem compatible with your logic. All the Intel boards used a constant
platform name matching the PCI ID, see e.g. [1], which IIRC is used to
bind components. Liam, do you recall in more details if this is really
required?
