[PATCH 2/2] hwmon/mc13783-adc: don't access struct mc13783 directly
There is a shiny new mc13783 API function that can be used instead. While at it refactor the code a bit to reduce code duplication a bit. This removes the last user of <linux/mfd/mc13783-private.h> and so this include file can go away. Signed-off-by: Uwe Kleine-König <u.kleine-koenig(a)pengutronix.de> --- dr... 2 Aug 2010 05:59
