      PCI: iproc: Propagate errors for optional PHYs · c1e33666
      Thierry Reding authored
      devm_phy_get() can fail for a number of reasons besides probe deferral.
      It can for example return -ENOMEM if it runs out of memory as it tries
      to allocate devres structures. Propagating only -EPROBE_DEFER is
      problematic because it results in these legitimately fatal errors being
      treated as "PHY not specified in DT".
      
      What we really want is to ignore the optional PHYs only if they have not
      been specified in DT. devm_phy_optional_get() is a function that exactly
      does what's required here, so use that instead.
