> When driver is built as module and DT node contains clocks compatible
> (e.g. "samsung,s2mps11-clk"), the module will not be autoloaded because
> module aliases won't match.
>
> The modalias from uevent: of:NclocksT<NULL>Csamsung,s2mps11-clk
> The modalias from driver: platform:s2mps11-clk

> The devices are instantiated by parent's MFD. However both Device Tree
> bindings and parent define the compatible for clocks devices. In case
> of module matching this DT compatible will be used.
>
> The issue will not happen if this is built-in (no need for module
> matching) or when clocks DT node does not contain compatible (not
> correct from bindings perspective but working for driver).
>
> Note when backporting to stable kernels: adjust the list of device ID
> entries.
