The definition of regulator_bulk_enable is fixed with __must_check
and this causes following build warning.
warning: ignoring return value of 'regulator_bulk_enable',
declared with attribute warn_unused_result
This patch fixes to check return value of the function.

Now it's not error case; having no return type, so just changed it into DRM_DEBUG_KMS. However, we need to add more exception codes to this function later.
Applied.
