Subject: Fix crash when a local deauth occurs (squash)
X-Git-Url: https://git.ti.com/gitweb?p=build-utilities%2Fhostap.git;a=commitdiff_plain;h=HEAD

Fix crash when a local deauth occurs (squash)

The check added in "Ignore a deauth from a different BSS than the current one"
didn't account for addr being null which may happen when the deauth
is locally generated.
