I found out that checkpatch has no check for this at all; it does
complain about such lines, but only for local variables. But that
warning is actually a bug, because this is a check for unary
operators: it thinks the asterisk is a dereference operator, not a
pointer declaration, and complains that the unary operator must be
preceded by a space. Thus warnings on local variable are only correct
by coincidence, not by design.

Inside structs or parameters (where my coding style violations can be
found), it's a different context and thus checkpatch doesn't apply the
rules for unary operators.
