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 4.4.131 upstream
stable 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 4.4.131 stable release shall be
applied:
* Linux 4.4.131
* serial: mctrl_gpio: Add missing module license
* serial: mctrl_gpio: export mctrl_gpio_disable_ms and mctrl_gpio_init
