mfd: constify regmap_irq_chip structures
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; @@ x@p @depends on !bad disable optional_qualifier@ identifier r.x; @@ +const struct regmap_irq_chip x; File size before: text data bss dec hex filename 5033 584 16 5633 1601 drivers/mfd/rk808.o File size after: text data bss dec hex filename 5225 392 16 5633 1601 drivers/mfd/rk808.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
