net/mlx5e: Don't use err uninitialized in mlx5e_attach_decap
Clang warns:
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:3712:6: warning:
variable 'err' is used uninitialized whenever 'if' condition is false
[-Wsometimes-uninitialized]
if (IS_ERR(d->pkt_reformat)) {
^~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:3718:6: note:
uninitialized use occurs here
if (err)
^~~
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:3712:2: note: remove the
'if' if its condition is always true
if (IS_ERR(d->pkt_reformat)) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:3670:9: note: initialize
the variable 'err' to silence this warning
int err;
^
= 0
1 warning generated.
It is not wrong, err is only ever initialized in if statements but this
one is not in one. Initialize err to 0 to fix this.
