From f616ab59c294b6ea6efa94f6139ea3eda2f52be0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 9 May 2018 06:53:49 +0200 Subject: dma-mapping: move the NEED_DMA_MAP_STATE config symbol to lib/Kconfig 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.
