iio: light: bh1750: constify attribute_group structures
Check for attribute_group structures that are only stored in the attrs filed of iio_info structure. As the attrs field of iio_info structures is constant, so these attribute_group structures can also be declared constant. Done using coccinelle: @r1 disable optional_qualifier @ identifier i; position p; @@ static struct attribute_group i@p = {...}; @ok1@ identifier r1.i; position p; struct iio_info x; @@ x.attrs=&i@p; @bad@ position p!={r1.p,ok1.p}; identifier r1.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r1.i; @@ static +const struct attribute_group i={...}; @depends on !bad disable optional_qualifier@ identifier r1.i; @@ +const struct attribute_group i; File size before: text data bss dec hex filename 2276 352 0 2628 a44 drivers/iio/light/bh1750.o File size after: text data bss dec hex filename 2340 320 0 2660 a64 drivers/iio/light/bh1750.o Signed-off-by: simran singhal <singhalsimran0@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
