This patch fixes a long standing issue introduced during the 3.16 merge window. Shortly after the merge, exynos5250-based arndale boards began to produce the following errors: kern.err kernel: exynos-cpufreq exynos-cpufreq: failed to set cpu voltage kern.err kernel: cpufreq: __target_index: Failed to change cpu frequency: -22 Further analysis revealed that the S5M8767 voltage regulator used on the exynos5250-based arndale board utilizes the S3C2410 I2C controller. If the S3C2410 I2C controller driver is not enabled, the S5M8767 voltage regulator fails to probe. Therefore a dependency exists between these two drivers. In the exynos_defconfig both CONFIG_REGULATOR_S5M8767 and CONFIG_I2C_S3C2410 options are enabled, and no errors are produced. However, in the multi_v7_defconfig only the CONFIG_REGULATOR_S5M8767 option is enabled and the errors are present. So let's enable the CONFIG_I2C_S3C2410 option in the multi_v7_defconfig to allow the S5M8767 voltage regulator to probe.
