Hi Ezequiel
Anybody writing device drivers should know about EPROBE_DEFER. If
they don't they are writing broken drivers. So putting in a comment
here would be just pointing out the obvious.
What i can however do is add a comment that devm_phy_get_optional()
returns a valid phy if there is no error. Might that help with the
confusion?
Thanks
Andrew
