That's exactly what the below patch does.

When NVMEM is configured as a loadable module, and adreno is built-in, we get a link failure: drivers/gpu/drm/msm/adreno/a5xx_gpu.o: In function `a5xx_gpu_init': a5xx_gpu.c:(.text+0x15cc): undefined reference to `nvmem_cell_get' a5xx_gpu.c:(.text+0x15da): undefined reference to `nvmem_cell_read' a5xx_gpu.c:(.text+0x15e4): undefined reference to `nvmem_cell_put' This adds a Kconfig dependency to enforce valid configurations, when NVMEM is a loadable module, adreno now has to also be one. The code seems to deal fine with nvmem being completely disabled, it will just not set the right speed bin then, so we don't need a hard dependency.
