I am a bit puzzled by all these add-top-level-constraint patches.
E.g. this file already constrains all of them below.
To me, it feels the same as a patch for driver code that would do:
+ if (param < 16 || param > 512)
+ return -EINVAL;
+
if (hw_variant_a) {
if (param < 16 || param > 256)
return -EINVAL;
...
} else if (hw_variant_b) {
if (param < 32 || param > 512)
return -EINVAL;
...
} else /* hw_variant_c */ {
if (param < 32 || param > 384)
return -EINVAL;
...
}
What's the point?
Thanks!
Gr{oetje,eeting}s,
