Subject: [IPV4]: Remove ifa != NULL check.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a337499f660ff70a12cea6607b9a64d7420e32dc;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[IPV4]: Remove ifa != NULL check.

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