Subject: Re: [PATCH] mfd: syscon: add inline nop functions to compile without option

> The syscon interface can be used in different drivers to reach registers
> of other register range via phandle. The exported functions can only be
> used if the syscon interface is enabled. This patch fixes this by
> adding nop functions if the syscon is not selected in the config.
