Bhumika Goyal af2708f5e8 Staging: most: aim-v4l2: constify v4l2_file_operations structures
Check for v4l2_file_operations structures that are only stored in the
fops field of video_device structures. As this field is constant, so
v4l2_file_operations structures having this property can also be
declared constant.
Done using coccinelle:

@r1 disable optional_qualifier @
identifier i;
position p;
@@
static struct v4l2_file_operations i@p = {...};

@ok1@
identifier r1.i;
position p;
struct video_device x;
@@
x.fops=&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 v4l2_file_operations i={...};
