Subject: Avoid use of a shadowed local variable
X-Git-Tag: hostap_2_9~149
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=09448d94a7c93edfd34ceec4dac16e390ef6bb6c;p=thirdparty%2Fhostap.git

Avoid use of a shadowed local variable

The same len variable can be used for both needs within
ieee802_1x_get_keys() to avoid compiler warning about use of shadowed
variable.

Fixes: 0ee6885dae04 ("macsec: Store EAP-Key-Name as eapSessionId")
