This amounts to saving 20 bytes of pointers, but the code bloats by 13 bytes because of reversion from register-indirect to direct addressing of dev_nm in several places. (Using [3] instead of [4] actually makes things worse because *3 isn't possible in the R/I/M byte). - Change dev_maj defn to "const unsigned char dev_maj[]" saves 15 bytes.
