From 63158d5c217e2e62665ae9b10d203bd7da817108 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 26 Apr 2008 22:25:21 +0200 Subject: ide: cleanup ide_setup_dma() * There is no need to call ide_release_dma_engine(). * Move the code up to (and including) ide_allocate_dma_engine() call to the callers of ide_setup_dma(). There should be no functional changes caused by this patch.
