Hi Bernard.

For example in exynos_dpi_probe() Is would be nice to only have to review for this type of changes once, so one patch-set is preferred over single patches over time. You can add: Reviewed-by: Sam Ravnborg <sam@ravnborg.org> to this patch when you re-send a new series.

I will re-check this part of the exynos driver code to see if there are similar patterns, and then re-send a patch series.
