Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/ethernet/mellanox/mlxsw/spectrum_qdisc.c: In function '__mlxsw_sp_qdisc_ets_graft':
drivers/net/ethernet/mellanox/mlxsw/spectrum_qdisc.c:770:7: error: 'p' undeclared (first use in this function); did you mean 'up'?
  770 |  if (!p->child_handle) {
      |       ^
      |       up

Caused by commit

  345457a6e2cd ("Merge remote-tracking branch 'net-next/master'")

i.e. an incorrect automatic merge between commit

  3971a535b839 ("mlxsw: spectrum_qdisc: Ignore grafting of invisible FIFO")

from Linus' tree and commit

  7917f52ae188 ("mlxsw: spectrum_qdisc: Generalize PRIO offload to support ETS")

from the net-next tree.

I have applied the following merge fix patch:
