Subject: [PATCH] XXX PCI/AER: remove unused variables
Date:   Tue,  2 Oct 2018 23:02:49 +0200
Message-Id: <20181002210426.2447078-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A couple of files now contain a function with a return
code variable that is no longer used:

drivers/net/ethernet/sfc/efx.c: In function 'efx_io_slot_reset':
drivers/net/ethernet/sfc/efx.c:3824:6: error: unused variable 'rc' [-Werror=unused-variable]
  int rc;
      ^~
drivers/net/ethernet/sfc/falcon/efx.c: In function 'ef4_io_slot_reset':
Oza Pawandeep <poza@codeaurora.org>
drivers/net/ethernet/sfc/falcon/efx.c:3163:6: error: unused variable 'rc' [-Werror=unused-variable]
  int rc;
      ^~
drivers/net/ethernet/intel/ixgbe/ixgbe_main.c: In function 'ixgbe_io_slot_reset':
drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:11143:6: error: unused variable 'err' [-Werror=unused-variable]
  int err;
      ^~~
drivers/net/ethernet/intel/i40e/i40e_main.c: In function 'i40e_pci_error_slot_reset':
drivers/net/ethernet/intel/i40e/i40e_main.c:14555:6: error: unused variable 'err' [-Werror=unused-variable]
  int err;

drivers/dma/ioat/init.c: In function 'ioat_pcie_error_slot_reset':
drivers/dma/ioat/init.c:1255:6: error: unused variable 'err' [-Werror=unused-variable]
  int err;

This removes all the ones I found during randconfig build testing.

Fixes: 6dcde3e574b2 ("XXX PCI/AER: Remove pci_cleanup_aer_uncorrect_error_status() calls")
