   3 Subject: [PATCH] eth: mtk_eth_soc: silence the GCC 12 array-bounds warning
   4
   5 GCC 12 gets upset because in mtk_foe_entry_commit_subflow()
   6 this driver allocates a partial structure. The writes are
   7 within bounds.
   8
   9 Silence these warnings for now, our build bot runs GCC 12
  10 so we won't allow any new instances.
