[PATCHv2 0/3] net: phy: prevent linking breakage

From: Alexandre Belloni
Date: Tue May 28 2013 - 07:43:58 EST


There is a linking issue when using phy_register_fixup{,_for_uid,_for_id} and
CONFIG_PHYLIB is not a builtin:

arch/arm/mach-at91/built-in.o: In function `ksz9021rn_phy_fixup':
:(.text+0x1174): undefined reference to `mdiobus_write'
:(.text+0x1188): undefined reference to `mdiobus_write'
:(.text+0x119c): undefined reference to `mdiobus_write'
:(.text+0x11b0): undefined reference to `mdiobus_write'
arch/arm/mach-at91/built-in.o: In function `sama5_dt_device_init':
:(.init.text+0x1e34): undefined reference to `phy_register_fixup_for_uid'

This has been solved for arch/arm/mach-mxs/ and arch/arm/mach-imx/ by testing
IS_BUILTIN(CONFIG_PHYLIB) before calling the functions.

The first patch is an attempt at solving that issue globally.

The following patches remove the unnecessary IS_BUILTIN(CONFIG_PHYLIB) checks.

Quickly greping into the code shows that the issue may arise in:

arch/powerpc/platforms/85xx/mpc85xx_mds.c
arch/arm/mach-davinci/board-dm644x-evm.c
arch/arm/mach-orion5x/dns323-setup.c
arch/arm/mach-at91/board-dt-sama5.c

Changes in v2:
- indentation fixes
- use static inline function instead of defines and return -ENOTSUPP

Alexandre Belloni (3):
net: phy: prevent linking breakage
arm: mxs: don't check for CONFIG_PHYLIB as builtin
arm: imx: don't check for CONFIG_PHYLIB as builtin
