Commit7495af9308("ARM: multi_v7_defconfig: Enable drivers for DragonBoard 410c") enables the CONFIG_PHY_QCOM_USB_HS for the ARM multi_v7_defconfig. Enabling this Kconfig is causing the kernel to crash on the Tegra20 Ventana platform in the ulpi_match() function. The Qualcomm USB HS PHY driver that is enabled by CONFIG_PHY_QCOM_USB_HS, registers a ulpi_driver but this driver does not provide an 'id_table', so when ulpi_match() is called on the Tegra20 Ventana platform, it crashes when attempting to deference the id_table pointer which is not valid. The Qualcomm USB HS PHY driver uses device-tree for matching the ULPI driver with the device and so fix this crash by using device-tree for matching if the id_table is not valid.
