From: Colin Ian King <colin.king@canonical.com>
Currently there are two error return paths that leak memory allocated to fib_work. Fix this by kfree'ing fib_work before returning.
Addresses-Coverity: ("Resource leak") Fixes: 19a9d136f198 ("ipv4: Flag fib_info with a fib_nh using IPv6 gateway") Fixes: dbcc4fa718ee ("rocker: Fail attempts to use routes with nexthop objects") Signed-off-by: Colin Ian King <colin.king@canonical.com> --- drivers/net/ethernet/rocker/rocker_main.c | 2 ++ 1 file changed, 2 insertions(+)
