Subject: dma-mapping: DMA_COHERENT_POOL should select GENERIC_ALLOCATOR
Git-commit: d07ae4c486908615ab336b987c7c367d132fd844
Patch-mainline: v5.8-rc3
References: bsc#1175898, ECO-2743
The dma coherent pool code needs genalloc. Move the select over
from DMA_REMAP, which doesn't actually need it.
Fixes: dbed452a078d ("dma-pool: decouple DMA_REMAP from DMA_COHERENT_POOL")
