Update to the 5.2 kernel plus my patches for the Nexus 5 display that will also work for other msm8974-based systems: https://github.com/masneyb/linux/commits/v5.2-nexus5-display. There's currently 25 extra patches on top of 5.2: - The first 9 patches after the 5.2 commit are currently in 5.3rc1 and were back ported to 5.2. All of these patches have 'Commit XXX upstream.' messages in the commit message. - The next 9 patches are for ocmem support and some msm display fixes. I expect that these will be merged upstream for 5.4rc1. - The remaining 7 patches are still not suitable to send upstream. [ci:skip-build]: already built successfully in CI
