Subject: [PATCH v3 04/11] dma-mapping: add <asm/dma-mapping.h> for all architectures
Date: Fri, 14 Feb 2020 16:40:20 +0900	[thread overview]
Message-ID: <20200214074027.19824-5-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <20200214074027.19824-1-yamada.masahiro@socionext.com>

To avoid "asm/dma-mapping.h: No such file or directory" error,
we need something.
