Strcmp() should not be used to check the phy_type string which maybe parsed by hwconfig_subarg(). Hwconfig_subarg() returns part of hwconfig string starting from phy_type value till the end of the string. Since phy_type could be either "utmi" or "ulpi", strncmp() should be used so that a comparison of "utmi;fsl_ddr:bank_intlv=auto" with "utmi" will succeed.
