Larry is the maintainer for rtl8712, so he'd be the one to answer
this. Out of the four drivers that are left using wext after
my current draft removal series, only ks7010 and rtl8712
use the private handlers, so in theory we could remove
the CONFIG_WEXT_PRIV first, but I'm not sure that makes
any difference if the plan is to convert all wext drivers
to cfg80211 anyway.
