The new PIO mode for the dwc audio driver causes a link failure when it is built as a loadable module but the audio driver is built-in: sound/built-in.o: In function `i2s_irq_handler': :(.text+0x58c64): undefined reference to `dw_pcm_push_tx' sound/built-in.o: In function `dw_i2s_probe': :(.text+0x593dc): undefined reference to `dw_pcm_register' We could link both into a single module, but apparently the author intended them to be separate, so this instead changes the Makefile to force the pcm module to be built-in if the base module is. This is a bit hacky but not as bad as trying to work around it in Kconfig language.
