Subject: video/mbx: constify fb_fix_screeninfo and fb_var_screeninfo structures
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1ccca3feff42765d60d68cf36af096a37056bc3b;p=openwrt%2Fstaging%2Fblogic.git

video/mbx: constify fb_fix_screeninfo and fb_var_screeninfo structures

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.
