This patch series can be applied to the media subsystem since it has no drm changes. Changes since the previous patch series are: - Added a new patch improving the documentation of the cec_transmit_done function to hopefully avoid the omap4 bug in the future. - Add a new patch that fixes a bug in the Signal Free Time calculation of the CEC framework. This affects hardware that relies on the framework for this value. This bug could basically cause a 'denial of service' situation on the CEC bus. Found with the cec-compliance adapter test, which does really nasty things :-) - Improve cec-gpio to fixup the Signal Free Time if a transmit is delayed because a new message was received first (thus requiring a lower SFT). All patches are meant for 4.20, and patches 2-5 will get a CC to stable for 4.18 and up. The adv patches could go back to older kernels, but it's not very important. I'll post a pull request for this series soon.
