Public bug reported:

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The v4.18.4 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.

       git://git.kernel.org/

    TEST CASE: TBD

       The following patches from the v4.18.4 stable release shall be
applied:

l2tp: use sk_dst_check() to avoid race on sk->sk_dst_cache
net_sched: fix NULL pointer dereference when delete tcindex filter
net_sched: Fix missing res info when create new tc_index filter
r8169: don't use MSI-X on RTL8168g
ALSA: hda - Sleep for 10ms after entering D3 on Conexant codecs
ALSA: hda - Turn CX8200 into D3 as well upon reboot
ALSA: vx222: Fix invalid endian conversions
ALSA: virmidi: Fix too long output trigger loop
