[PATCH/RFC 0/3] of/overlay: Update aliases when added or removed

[Geert Uytterhoeven]

	Hi,

Currently the list of aliases is not updated when a DT overlay that adds
an alias is loaded or unloaded. This break drivers (e.g. serial) that
rely on of_alias_get_id(). This RFC patch series fixes that.

This is definitely not a final solution to be applied, as (1) it doesn't
fix all possible cases, and as (2) there's an unresolved issue w.r.t.
object lifetime. More about this in the last patch.

But it's Good Enough For My Use Case(TM), which is enabling/disabling
serial ports on expansion headers by (un)loading DTBOs.

Thanks for your comments!
