From ead841c2ed986f7cc6a4830e816b0f633f95cf7f Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 18 Aug 2011 20:16:56 +0900 Subject: ARM: S3C24XX: Remove hw_addr from s3c24xx dma channel declarations According to commit c4806174c516d26bf4a72db1789cfc96e4950d07 (ARM: S3C2412: DMA: Remove I2S FIFO address) the S3C DMA API does not make use of hw_addr.to/from declared for some of the channels in mach-s3c24XX/dma.c Grepping through the kernel also did non reveal any new users of these properties since the mentioned commit.
