This makes linux-next fail the modules_install target as depmod detects 2 circular
dependencies. Reverting this patch fixes the issue.

depmod: ERROR: Cycle detected: libphy -> of_mdio -> fixed_phy -> libphy
depmod: ERROR: Cycle detected: libphy -> of_mdio -> libphy
depmod: ERROR: Found 3 modules in dependency cycles!
make[1]: *** [/home/dliviu/devel/kernel/Makefile:1245: _modinst_post] Error 1

This is on an ARCH=arm build, build I doubt it makes a difference. Let me know if
you need some .config values in order to reproduce.

Best regards,
