Subject: [IPV6]: Make fib6_init to return an error code.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d63bddbe90c4fd924b2155ca92a879393d856170;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[IPV6]: Make fib6_init to return an error code.

If there is an error in the initialization function, nothing is
followed up to the caller. So I add a return value to be set for the
init function.
