From e3e01d6005ab4b0877f1fb3efef7f5b745e743be Mon Sep 17 00:00:00 2001 From: "Eddie C. Dost" Date: Wed, 6 Jul 2005 15:41:54 -0700 Subject: [PATCH] [SPARC64]: Fix enable_dma() in asm-sparc64/parport.h Call ebus_dma_enable() before calling ebus_dma_request(), otherwise ebus_dma_request() returns -EINVAL and enable_dma() calls BUG()...
