[PATCH 06/12] dma-mapping: move the NEED_DMA_MAP_STATE config symbol to lib/Kconfig

2018-04-23 Thread Christoph Hellwig 
This way we have one central definition of it, and user can select it as
needed.  Note that we now also always select it when CONFIG_DMA_API_DEBUG
is select, which fixes some incorrect checks in a few network drivers.
