Hi Arnd,

FYI, the error/warning still remains.

synclink.c:(.text+0xd1a): undefined reference to `free_dma'

This can be addressed by either backporting f95a387cdeb3 ("m68k: coldfire: drop ISA_DMA_API support") or by reverting the 87ae522e467e ("m68knommu: only set CONFIG_ISA_DMA_API for ColdFire sub-arch"), which is not actually needed on 5.10.

I've now reverted it, thanks.
