From: Arnd Bergmann When CONFIG_FIXED_PHY is in a loadable module, the fec driver cannot be built-in any more: x86_64-linux-ld: vmlinux.o: in function `fec_enet_mii_probe': fec_main.c:(.text+0xc4f367): undefined reference to `fixed_phy_unregister' x86_64-linux-ld: vmlinux.o: in function `fec_enet_close': fec_main.c:(.text+0xc59591): undefined reference to `fixed_phy_unregister' x86_64-linux-ld: vmlinux.o: in function `fec_enet_mii_probe.cold': Select the fixed phy support on all targets to make this build correctly, not just on coldfire. Notat that Essentially the stub helpers in include/linux/phy_fixed.h cannot be used correctly because of this build time dependency, and we could just remove them to hit the build failure more often when a driver uses them without the 'select FIXED_PHY'. Fixes: dc86b621e1b4 ("net: fec: register a fixed phy using fixed_phy_register_100fd if needed") Signed-off-by: Arnd Bergmann --- I sent the same fix for B44 earlier, see commit 3f0f591b44b0 ("net: b44: always select CONFIG_FIXED_PHY"). I checked that there are no other conditional users of FIXED_PHY this time. --- drivers/net/ethernet/freescale/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ethernet/freescale/Kconfig b/drivers/net/ethernet/freescale/Kconfig index e2a591cf9601..11edbb46a118 100644 --- a/drivers/net/ethernet/freescale/Kconfig +++ b/drivers/net/ethernet/freescale/Kconfig @@ -28,7 +28,7 @@ config FEC depends on PTP_1588_CLOCK_OPTIONAL select CRC32 select PHYLIB - select FIXED_PHY if M5272 + select FIXED_PHY select PAGE_POOL imply PAGE_POOL_STATS imply NET_SELFTESTS -- 2.39.5
