We still have prefixes (and compatibles) from entities which disappeared
(e.g. Freescale) but these were added probably before the
merge/acquisition happened. In this case, I do not see a benefit of
adding a vendor prefix of non-existing vendor.

Therefore use avnet as vendor in compatible. The model name of course
can stay MSC or whatever you prefer.
