[PATCH v12 5/9] staging: hi6421-spmi-pmic: cleanup drvdata

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
