Hi Greg,
While looking at android-4.14, I found a NULL pointer deref with stm32-dma driver using Coccicheck errors. I found that upstream had a bunch of patches on stm32-dma that have fixed this and other issues, I applied these patches cleanly onto Android 4.14. I believe these should goto stable and flow into Android 4.14 from there, but I haven't tested this since I have no hardware to do so.
Atleast I can say that the coccicheck error below goes away when running: make coccicheck MODE=report ./drivers/dma/stm32-dma.c:567:18-24: ERROR: chan -> desc is NULL but dereferenced.
Anyway, please consider this series for 4.14 stable, I have CC'd the author and others, thanks.

It would be good to only cherry pick fixes for this. I do not feel that some of them which are adding or enhancing driver belong to stable.
Thanks
