"We also" wording is nearly always a hint, that this should be done
in two independent patches.

As you told me the driver will be upstreamed in April, please add this flag when

Add each flag when you add the user of the flag.

NAK, this will not compile. Please make sure that every patch on it's own does
not break compilation.
