From a2d0dbb4b55681874c5f288538ae55ae69baeaff Mon Sep 17 00:00:00 2001 From: Xiong Zhou Date: Tue, 7 May 2013 10:15:56 +0800 Subject: bq27x00: Fix I2C dependency in KConfig This patch fixes build failure(randconfig) of next-20130501. When config I2C as m, BATTERY_BQ27x00 as y, here comes the failure. The driver depends on I2C only if I2C is not disabled, as Lars commented. Last version of this patch make the driver depend on I2C unconditionally.
