Subject: PASN: Clear extra_ies_len to 0 on freeing extra_ies
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=afdf372ce9df1b08ede86159facc553fd216dfc2;p=thirdparty%2Fhostap.git

PASN: Clear extra_ies_len to 0 on freeing extra_ies

There is no point in setting extra_ies_len to the new value in
pasn_set_extra_ies() at the point when the old value is freed. This
setting happens already at the appropriate place after the new value has
been successfully assigned. Set extra_ies_len to 0 here so that it will
have value 0 in case the allocation fails and leaves extra_ies to NULL.
