From dc844e05913b84d09e86d88c0f861ef0afbee2fd Mon Sep 17 00:00:00 2001 From: Sergei Shtylylov Date: Tue, 3 Oct 2006 01:14:14 -0700 Subject: [PATCH] [PATCH] IDE: always release DMA engine Release the DMA engine for the custom mapping IDE drivers also (for example, siimage.c does allocate it in both I/O-mapped and custom-mapped modes). Remove useless code from the error path of ide_allocate_dma_engine().
