The Ralink MIPS platform does not use Common Clock Framework and does not define certain clock operations leading to compile test failures: /usr/bin/mips-linux-gnu-ld: drivers/usb/phy/phy-tegra-usb.o: in function `tegra_usb_phy_init': phy-tegra-usb.c:(.text+0x1dd4): undefined reference to `clk_get_parent' Reported-by: kernel test robot <lkp@xxxxxxxxx> Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxxxxx> Acked-by: John Crispin <john@xxxxxxxxxxx> --- Changes since v1: 1. Use EXPORT_SYMBOL_GPL like two other stubs in the file. 2.
