From 40a2945b97b4da9120653d84f1c3a58fe58be64c Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 6 Apr 2009 19:00:38 -0700 Subject: Blackfin SPI Driver: do not check for SPI errors if DMA itself did not flag any We only need to check SPI error when DMA failes, cause that is the DMA IRQ handling routine.
