From: Andy Shevchenko Date: Tue, 13 Jan 2015 17:08:14 +0000 (+0200) Subject: dmaengine: dw: define DW_DMA_MAX_NR_MASTERS X-Git-Tag: fixes-v4.0-rc1~64^2~17 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d8ded50f8b26a224df48f9f93e49440c6a39b77f;p=pandora-kernel.git 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.
