Subject: [PATCH] mfd: omap-usb-host: Fix OF populate on driver rebind
Since commit c6e126de43e7 ("of: Keep track of populated platform
devices") child devices will not be created by of_platform_populate()
if the devices had previously been deregistered individually so that the
OF_POPULATED flag is still set in the corresponding OF nodes.
Switch to using of_platform_depopulate() instead of open coding so that
the child devices are created if the driver is rebound.
Fixes: c6e126de43e7 ("of: Keep track of populated platform devices")
