Subject: kernel-2.eclass: avoid lexicographical compare on versions, bug #705246
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c54b9d619157d9a24e72f04d5698a00ee9a368dd;p=gentoo.git

kernel-2.eclass: avoid lexicographical compare on versions, bug #705246

Originally found in bug #705240 as:

```
if [[ ... || ${KV_MAJOR}.${KV_MINOR}.${KV_PATCH} > 2.6.28 ]]; then
```

'>' are string comparisons. They are benign so far, but
will start failing on linux-10 :)

Let's be consistent and use version comparison.

Closes: https://bugs.gentoo.org/705246
