SubjectRe: [PATCH -next] power: fix bq27x00_battery kconfig
From: Xiong Zhou <jencce.kernel@gmail.com>

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.

Failure message:
drivers/built-in.o: In function `bq27x00_read_i2c':
bq27x00_battery.c:(.text+0x1082a7): undefined reference to `i2c_transfer'
