      net: xgene: Check negative return value of xgene_enet_get_ring_size() · 9b9ba821
      Tobias Klauser authored
      xgene_enet_get_ring_size() returns a negative value in case of an error,
      but its only caller in xgene_enet_create_desc_ring() currently uses the
      return value directly as u32. Instead, check for a negative value first and
      error out in case. Also move the call to xgene_enet_get_ring_size() before
      devm_kzalloc() so we don't need to free anything in the error path.
      This fixes the following issue reported by the Coverity Scanner:
      ** CID 1231336:  Improper use of negative value  (NEGATIVE_RETURNS)
      /drivers/net/ethernet/apm/xgene/xgene_enet_main.c: 596 in xgene_enet_create_desc_ring()
