Subject: [net: PATCH] net: mvmdio: fix compilation warning
Date: Mon, 15 Nov 2021 16:30:24 +0100	[thread overview]
Message-ID: <20211115153024.209083-1-mw@semihalf.com> (raw)

The kernel test robot reported a following issue:

>> drivers/net/ethernet/marvell/mvmdio.c:426:36: warning:
unused variable 'orion_mdio_acpi_match' [-Wunused-const-variable]
   static const struct acpi_device_id orion_mdio_acpi_match[] = {
                                      ^
   1 warning generated.

Fix that by surrounding the variable by appropriate ifdef.

Fixes: c54da4c1acb1 ("net: mvmdio: add ACPI support")
