Subject: [PATCH] net-ipv6: addrconf_f6i_alloc - fix non-null pointer check to !IS_ERR()
Date: Thu,  5 Sep 2019 20:56:37 -0700	[thread overview]
Message-ID: <20190906035637.47097-1-zenczykowski@gmail.com> (raw)
In-Reply-To: <CANP3RGcbEP2N-CDQ6N649k0-cV4AhQeWqF-niz7EMPFOFpkU1w@mail.gmail.com>

From: Maciej Żenczykowski <maze@google.com>

Fixes a stupid bug I recently introduced...
ip6_route_info_create() returns an ERR_PTR(err) and not a NULL on error.

Fixes: d55a2e374a94 ("net-ipv6: fix excessive RTF_ADDRCONF flag on ::1/128 local route (and others)'")
