Could you take a closer look and fix similar patterns
in the rest of the driver?
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:

to this patch when you re-send a new series.

Thanks,
