From d8ded50f8b26a224df48f9f93e49440c6a39b77f Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 13 Jan 2015 19:08:14 +0200 Subject: dmaengine: dw: define DW_DMA_MAX_NR_MASTERS Instead of using magic number in the code the patch provides DW_DMA_MAX_NR_MASTERS constant. While here, restrict the reading of data width array by amount of the actual number of AHB masters.
