| |
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.
