My mistake, I had squashed two build fixes for the same driver but
forgot to update the changelog with the other output. This is what
happens without CONFIG_COMMON_CLK:

arm-linux-gnueabi-ld: drivers/phy/mediatek/phy-mtk-hdmi.o: in function
`mtk_hdmi_phy_probe':
phy-mtk-hdmi.c:(.text+0xd8): undefined reference to `__clk_get_name'
arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x12c): undefined
reference to `devm_clk_register'
arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x250): undefined
reference to `of_clk_add_provider'
arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x298): undefined
reference to `of_clk_src_simple_get'

I'll resend with that added in.
