No, that's foolish.

checkpatch is a hint, it's not always right.

Also, checkpatch cleanups for really old drivers is not generally a good
idea, especially if you do not have the hardware for them.  Please don't
cause unneeded churn for this type of thing in this subsystem, unless
you have the hardware.
