From: Arnd Bergmann <arnd@xxxxxxxx> The added lvds driver and a change in the dsi driver resulted in failed builds when COMMON_CLK is disabled: x86_64-linux-ld: drivers/gpu/drm/stm/dw_mipi_dsi-stm.o: in function `dw_mipi_dsi_stm_remove': dw_mipi_dsi-stm.c:(.text+0x51e): undefined reference to `clk_hw_unregister' x86_64-linux-ld: drivers/gpu/drm/stm/lvds.o: in function `lvds_remove': lvds.c:(.text+0xe3): undefined reference to `of_clk_del_provider' x86_64-linux-ld: lvds.c:(.text+0xec): undefined reference to `clk_hw_unregister' x86_64-linux-ld: drivers/gpu/drm/stm/lvds.o: in function `lvds_pll_config': lvds.c:(.text+0xb5d): undefined reference to `clk_hw_get_rate' x86_64-linux-ld: drivers/gpu/drm/stm/lvds.o: in function `lvds_probe': lvds.c:(.text+0x1476): undefined reference to `clk_hw_register' x86_64-linux-ld: lvds.c:(.text+0x148b): undefined reference to `of_clk_hw_simple_get' x86_64-linux-ld: lvds.c:(.text+0x1493): undefined reference to `of_clk_add_hw_provider' x86_64-linux-ld: lvds.c:(.text+0x1535): undefined reference to `clk_hw_unregister' Add this as a dependency for the stm driver itself, since it will be required in practice anyway.
