From 4397c98a8a60ba029f2d0051d0cbafe600f05d8c Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 30 Jun 2010 01:40:52 -0700 Subject: Input: ad7879 - split bus logic out The ad7879 driver is using the old bus method of only supporting one at a time (I2C or SPI). So refactor it like the other input drivers that support multiple busses simultaneously.
