I think checkpatch already has gone way too far with this (and not
only this).

"type *var" vs "type* var" - sure, the latter is worse and provokes
"type* var1, var2", but anything else is IMHO only annoying and,
actually, not important WRT readability at all.

For example I prefer "type* func()" - as it's a function returning
"a pointer to type" and not "a pointer to a function returning type"
(which "type *func()" may suggest). Yes, func is not a pointer, so why
write "*" next to it?
