Bhumika Goyal d983c59775 Staging: most: hdm-dim2: constify attribute_group structures

Check for attribute_group structures that are only passed as a second
argument to the functions sysfs_remove_group and sysfs_create_group. As
these arguments are constant so, attribute_group structures having this
property can also be made constant.
Done using coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct attribute_group i@p = {...};

@ok1@
identifier r1.i;
position p;
expression e1,e2;
@@
(
sysfs_remove_group(e1,&i@p)
|
sysfs_create_group(e1,&i@p)
)

@bad@
position p!={r1.p,ok1.p};
identifier r1.i;
@@
i@p

@depends on !bad disable optional_qualifier@

struct attribute_group i={...};
