Subject: [PATCH AUTOSEL 4.9 18/35] drivers: net: xgene: Remove unnecessary forward declarations

From: Nathan Chancellor <natechancellor@...il.com>

[ Upstream commit 2ab4c3426c0cf711d7147e3f559638e4ab88960e ]

Clang warns:

drivers/net/ethernet/apm/xgene/xgene_enet_main.c:33:36: warning:
tentative array definition assumed to have one element
static const struct acpi_device_id xgene_enet_acpi_match[];
                                   ^
1 warning generated.

Both xgene_enet_acpi_match and xgene_enet_of_match are defined before
their uses at the bottom of the file so this is unnecessary. When
CONFIG_ACPI is disabled, ACPI_PTR becomes NULL so xgene_enet_acpi_match
doesn't need to be defined.
