As I wrote earlier, this driver in it's current form is pretty much
useless. The BU27034NUC was cancelled and, as far as I know, never
produced "en masse". The replacement, BU27034ANUC, has undergone
somewhat meaningful changes like removal of one of the data channels -
so this driver is not producing correct results on that IC.

I have promised to rework this driver to support the new variant, and I
have this new HW on my table - but I am currently negotiating to be able
to provide an open-source Lux calculation formula in the driver... This
is causing some slight delay.

So, I think applying this patch is still worth :)
