Subject: BUILD: h3: fix compilation with USE_TRACE=0
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3dfd86062b9edf30f48701413ade565d67d3c1bb;p=thirdparty%2Fhaproxy.git

BUILD: h3: fix compilation with USE_TRACE=0

Mark argument in h3_trace_header as unused if USE_TRACE is not set.

No need to backport unless HTTP/3 header traces are picked.
