Subject: tc: m_gate: use SPRINT_BUF when needed
X-Git-Tag: v5.11.0~6
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=546f738220e7d492d3ea47d4b85f11487a0dae87;p=thirdparty%2Fiproute2.git

tc: m_gate: use SPRINT_BUF when needed

sprint_time64() uses SPRINT_BSIZE-1 as a constant buffer lenght in its
implementation, however m_gate uses shorter buffers when calling it.

Fix this using SPRINT_BUF macro to get the buffer, thus getting a
SPRINT_BSIZE-long buffer.
