Subject: [PATCH] mfd: omap-usb-host: Fix dts probe of children
Git-commit: 10492ee8ed9188d6d420e1f79b2b9bdbc0624e65
Patch-mainline: v4.19-rc5
References: bsc#1051510
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.
