Subject: [STRIP]: Fix neighbour table refcount leak.
X-Git-Tag: v6.6-pxa1908~58851^2
X-Git-Url: https://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ee1377c3eef4238d89b2f99fa4d0bbbad3078b64;p=linux.git

[STRIP]: Fix neighbour table refcount leak.

Found by inspection. The STRIP driver does neigh_lookup() but never
releases.  This driver shouldn't being doing gratuitous arp anyway.

Untested, obviously, because of lack of hardware.
