Subject: [PATCH lksctp-tools] travis: use git instead of downloading tarballs
Message-Id: <61414c1f14e60615bd2c2235dca6797baa1c0783.1533141162.git.marcelo.leitner@gmail.com>

MIME-Version: 1.0
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: 7bit
To: linux-sctp@vger.kernel.org

With this, we 1) avoid downloading several tarballs and 2) make it
easier to test against Linus master.

We want to test against Linus master so can catch build errors before
GA, like the one fixed by Xin's patches in the sequence.

Sample build: https://travis-ci.org/sctp/lksctp-tools/builds/410860154
