Could you instead make the drivers compile without OF being set?

I see that patch 7 and 8 introduces another two options doing


+config SND_SOC_LPASS_APQ8016
+       tristate
+       depends on SND_SOC_QCOM
+       select SND_SOC_LPASS_CPU
+       select SND_SOC_LPASS_PLATFORM
+

+config SND_SOC_APQ8016_SBC
+       tristate "SoC Audio support for APQ8016 SBC platforms"
+       depends on (ARCH_QCOM && SND_SOC_QCOM) || COMPILE_TEST
+       select SND_SOC_LPASS_APQ8016
+       help

so you get an obvious build failure here when SND_SOC_APQ8016_SBC
gets selected with COMPILE_TEST on a platform that does not support OF.
