[PATCH v8 02/10] mfd: axp20x: Remove second struct device * parameter for axp20x_match_device()

From: Chen-Yu Tsai
Date: Thu Feb 11 2016 - 21:05:23 EST


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.
