    mfd: constify regmap_irq_chip structures · 24e34b9d
    Bhumika Goyal authored
    Declare regmap_irq_chip structures as const as they are only stored
    in the regmap_irq_chip field of a rk808 structure. This field is of
    type const, so regmap_irq_chip structures having this property can be
    made const too.
    Done using Coccinelle:
    
    @r disable optional_qualifier@
    identifier x;
    position p;
    @@
    static struct regmap_irq_chip x@p={...};
    
    @ok@
    struct rk808 a;
    identifier r.x;
    position p;
    @@
    a.regmap_irq_chip=&x@p;
    
    @bad@
    position p != {r.p,ok.p};
    identifier r.x;
