Subject: [IPV4]: Remove check for ifa->ifa_dev != NULL.
X-Git-Tag: v2.6.26-rc1~1138^2~571
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5811769c788edbf379c8b3fc65f62394d52df748;p=linux-2.6

[IPV4]: Remove check for ifa->ifa_dev != NULL.

This is a callback registered to inet address notifier chain.
The check is useless as:
- ifa->ifa_dev is always != NULL
- similar checks are abscent in all other notifiers.
