[PATCH v6 2/9] mfd: axp20x: Remove second struct device * parameter for axp20x_match_device()

Show all headers | View raw

The first argument passed to axp20x_match_device(), struct axp20x_dev *,
already contains a pointer to the device. By rearranging some code,
moving the assignment of the pointer before axp20x_match_device() is
called, we can eliminate the second parameter.
