Subject: Re: [RESUBMIT RFC PATCH v2 3/3] drivers: mfd: Add support for Exynos
 PMU driver

> This patch moves Exynos PMU driver implementation from
> "arm/mach-exynos" to "drivers/mfd".
> This driver is mainly used for setting misc bits of register from PMU IP
> of Exynos SoC which will be required to configure before Suspend/Resume.
> Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but
> moving ahead for ARM64 based SoC support, there is a need of DT based
> implementation of PMU driver.
> This driver uses already existing DT binding information.

The help should be indented. Take a look at the other entries.
