Unless I am mistaken, the link you provided refers to a PowerPC linker error: [...] compiler: powerpc-linux-gcc (GCC) 14.1.0 [...] powerpc-linux-ld: drivers/gpu/drm/stm/dw_mipi_dsi-stm.o: in function `dw_mipi_dsi_stm_remove': dw_mipi_dsi-stm.c:(.text+0x664): undefined reference to `of_clk_del_provider' >> powerpc-linux-ld: dw_mipi_dsi-stm.c:(.text+0x66c): undefined reference to `clk_hw_unregister' powerpc-linux-ld: drivers/gpu/drm/stm/dw_mipi_dsi-stm.o: in function `dw_mipi_dsi_stm_probe': dw_mipi_dsi-stm.c:(.text+0x98c): undefined reference to `clk_hw_register' > > So I think you should send that patch to Linus now so that such randconfig > builds do not fail anymore. What do you mean by 'sending it to Linus' ? If you meant to do a pull request, then no. This patch is already in the drm-misc tree, which means it will keep its usual pace of merging with the rest of the drm-misc tree.

Thank you for this. Do not hesitate to reach if you encounter any problems with this patch. Regards, Raphaël > > Thx. >
