Remove unneeded _orig variable, which stores
pointer to tokenized string. Unlike strsep(), strtok()
doesn't modify pointer itself, only string, so it is safe
to call free() on that pointer.

Can we just wait with style patches like that that create conflicts with
 a large patchset like my NCP patchset until those larger patches are
handled?
