[PATCH AUTOSEL 4.4 04/11] mfd: omap-usb-host: Fix dts probe of children

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tony Lindgren <tony@xxxxxxxxxxx>

[ Upstream commit 10492ee8ed9188d6d420e1f79b2b9bdbc0624e65 ]

It currently only works if the parent bus uses "simple-bus". We
currently try to probe children with non-existing compatible values.
And we're missing .probe.

I noticed this while testing devices configured to probe using ti-sysc
interconnect target module driver. For that we also may want to rebind
the driver, so let's remove __init and __exit.
