In the case of the mdio mux code, I'm dropping the reference when
either (a) we've encountered an error during initialisation and
we're cleaning up, or (b) when the mdio mux code is being torn down
after the mdiomux bus has been unregistered and freed.  In both
cases, we're done with the mdio bus that was returned from
of_mdio_find_bus().

In case (a), the devres code will release the kmalloc'd memory when
mdio_mux_gpio_probe() or mdio_mux_mmioreg_probe() propagates the error
out of their probe() function.

I'm not sure why you think anything is wrong here - maybe it's the odd
code structure to the success path at the bottom of mdio_mux_init()?

Ok I may have misread your change.  I'll restudy it when you respin
the series with the commit message fixed and the DSA change added.

Thanks.
