Syncookie validation may fail for OoO packets, causing spurious resets and self-tests failures, so let's force syncookie only for tests iteration with no OoO. Fixes: fed61c4 ("selftests: mptcp: make 2nd net namespace use tcp syn cookies unconditionally") Closes: multipath-tcp/mptcp_net-next#198 Signed-off-by: Paolo Abeni <pabeni@redhat.com>

Commit a0384ec ("clk: qcom: smd-rpm: De-duplicate identical entries") introduces the following regression on MSM8936/MSM8939, as RPM_SMD_PCNOC_A_CLK gets pointed to pcnoc_clk by mistake. Fix it by correcting the clock to pcnoc_a_clk.
