Hi,
Linux next-20130702 link broke for ARM config multi_v7_defconfig. This is with
gcc 4.7.2 but I am not sure it matters much here.
This patch repairs the link.
It did not break anything for me on i.MX6 sabre sd, but it does'nt have a
designware i2c, so more reviewing/testing is welcome.
Best regards,
V.
