Subject: [IPV4]: Fix error handling for fib_insert_node call
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b47b2ec19892ffc2b06ebf138ed4aa141275a1c2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[IPV4]: Fix error handling for fib_insert_node call

The error handling around fib_insert_node was broken because we always
zeroed the error before checking it.
