    ARM: shmobile: rcar-gen2: Add missing of_node_put()
    
    [ Upstream commit 85744f2d938c5f3cfc44cb6533c157469634da93 ]
    
    Fix following coccicheck warning:
    ./arch/arm/mach-shmobile/regulator-quirk-rcar-gen2.c:156:1-33: Function
    for_each_matching_node_and_match should have of_node_put() before break
    and goto.
    
    Early exits from for_each_matching_node_and_match() should decrement the
    node reference counter.
