| |
exynos5_counters_get() might fail with -EPROBE_DEFER if the driver for devfreq event counter is not yet probed. Propagate that error value to the caller to ensure that the exynos5422-dmc driver will be probed again when devfreq event contuner is available.
This fixes boot hang if both exynos5422-dmc and exynos-ppmu drivers are compiled as modules.
