Subject: [PATCH] net: fec: make FIXED_PHY dependency unconditional

From: Arnd Bergmann <[email-masked]>

From: Arnd Bergmann <[email-masked]>

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'.

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.
