These structures are only used to copy into other structures,
so declare them as const.
This issue was detected using Coccinelle and the following semantic patch:
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct fb_fix_screeninfo i@p = { ... };
@ok@
identifier r.i;
expression e;
position p;
@@
e = i@p
@bad@
position p != {r.p,ok.p};
identifier r.i;
struct fb_fix_screeninfo e;
@@
e@i@p
@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
struct fb_fix_screeninfo i = { ... };
The semantic patch for fb_var_screeninfo is analogous.
