From 3be53f3f213223f50d8e29b5e1869685bf040a1e Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Wed, 16 Jul 2008 20:33:36 +0200 Subject: ide: move some bits from ide-timing.h to Move struct ide_timing and IDE_TIMING_* defines to from drivers/ide/ide-timing.h. While at it: - use u8/u16 instead of short for struct ide_timing fields - use enum for IDE_TIMING_* There should be no functional changes caused by this patch.
