net/bluetooth/mgmt.c:905:6-13: WARNING: kzalloc should be used for rp, instead
of kmalloc/memset
Use kzalloc rather than kmalloc followed by memset with 0
This considers some simple cases that are common and easy to validate
Note in particular that there are no ...s in the rule, so all of the
matched code has to be contiguous
