Subject: [PATCH v14 5/9] staging: hi6421-spmi-pmic: cleanup drvdata
There are lots of fields at struct hi6421_spmi_pmic that aren't
used. In a matter of fact, only regmap is needed.
So, drop the struct as a hole, and set just the regmap as
the drvdata.
While here, add a missing dot at the Huawei's copyrights.
