| Message-ID | <qsR5D-4AF-5@gated-at.bofh.it> |
If NO_DMA=y:
ERROR: "dma_free_coherent" [drivers/hwtracing/intel_th/intel_th_msu.ko] undefined!
ERROR: "dma_alloc_coherent" [drivers/hwtracing/intel_th/intel_th_msu.ko] undefined!
ERROR: "dma_supported" [drivers/hwtracing/intel_th/intel_th.ko] undefined!
Add a dependency on HAS_DMA to fix this.
