What PHK means is that if this driver is both for 5.x and 4.x,
then you should only register its major in RELENG_4 -- 5.x
provides automatic major numbers allocations:

: /*
:  * XXX: do not use MAJOR_AUTO unless you have no choice.  In general driv=
ers
:  * should just not initialize .d_maj and that will DTRT.
:  */
: #define MAJOR_AUTO      0       /* XXX: Not GM */
