Subject: [PATCH] [net-next] xgene_enet: remove bogus forward declarations
The device match tables for both the xgene_enet driver and its phy driver
have forward declarations that declare an array without a length, leading
to a clang warning when they are not followed by an actual defitinition:
drivers/net/ethernet/apm/xgene/../../../phy/mdio-xgene.h:135:34: warning: tentative array definition assumed to have one element
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:33:36: warning: tentative array definition assumed to have one element
The declarations for the mdio driver are even in a header file, so they
cause duplicate definitions of the tables for each file that includes
them.
This removes all four forward declarations and moves the actual
definitions up a little, so they are in front of their first user. For
the OF match tables, this means having to remove the #ifdef around them,
and passing the actual structure into of_match_device(). This has no
effect on the generated object code though, as the of_match_device
function has an empty stub that does not evaluate its argument, and
the symbol gets dropped either way.
Fixes: 43b3cf6634a4 ("drivers: net: phy: xgene: Add MDIO driver")
Signed-off-by: Arnd Bergmann <arnd@...db.de>

The bug is old, but relatively harmless, so not needed as a fixup for 4.10
