Subject[PATCH v2 06/26] drm: sun4i: Define and use generic PM ops
Date
Use the new DEFINE_DRM_MODE_CONFIG_HELPER_PM_OPS() macro to create a
"struct dev_pm_ops" that can be used by this driver, instead of using
custom PM callbacks with the same behaviour.

v2: Use the DEFINE_DRM_MODE_CONFIG_HELPER_PM_OPS() macro instead of an
exported dev_pm_ops.

Samuel: since the code changed I had to remove your reviewed-by, sorry
about that.
