[PATCH 6.0 852/862] net: ethernet: ti: davinci_mdio: fix build for mdio bitbang uses

From: Greg Kroah-Hartman
Date: Wed Oct 19 2022 - 05:45:59 EST


From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

commit 35bbe652c421037822aba29423f5f1f7d0d69f3f upstream.

davinci_mdio.c uses mdio bitbang APIs, so it should select
MDIO_BITBANG to prevent build errors.

arm-linux-gnueabi-ld: drivers/net/ethernet/ti/davinci_mdio.o: in function `davinci_mdio_remove':
drivers/net/ethernet/ti/davinci_mdio.c:649: undefined reference to `free_mdio_bitbang'

drivers/net/ethernet/ti/davinci_mdio.c:545: undefined reference to `alloc_mdio_bitbang'
