Subject: Remove a static analyzer warning about unused variable write
X-Git-Tag: hostap_2_2~687
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e997bc75dd58adee7b1ff9598e2ac994d4c0d31a;p=thirdparty%2Fhostap.git

Remove a static analyzer warning about unused variable write

The pos variable was not used between its first and second assignment.
Clean this up by using the pos variables instead of the buf (start of
the buffer).
