    Subject[PATCH 4.9 181/223] mfd: core: Set fwnode for created devices
    Date
    [ Upstream commit c176c6d7e932662668bcaec2d763657096589d85 ]

    The logic for setting the of_node on devices created by mfd did not set
    the fwnode pointer to match, which caused fwnode-based APIs to
    malfunction on these devices since the fwnode pointer was null. Fix
    this.
