I tried to test this on my s3c64xx based system but it gave me a kernel
that didn't boot far enough to give console output (there's some early
init stuff that uses SPI...). That said, I needed:
diff --git a/drivers/dma/amba-pl08x.c b/drivers/dma/amba-pl08x.c
index 210a893..0f49707 100644

return ret;
to get it to build which makes me suspect the compiler a bit as well...
the system has audio, SPI and MMC enabled.
I was applying this to -next, are there any other dependencies I need or
anything?
