This has to be told in the commit message. Anyway, we don't need a duplication
code, please use 8250_pnp.

Does it have _CID to be PNP0501?
If not, add this ID to the 8250_pnp.

P.S.
The code you submitted has a lot of small style issues, I can comment on them
if you want, but as I said this code is not needed at all.
