Subject:    [2.6 patch] IDE: possible cleanups
From:       Adrian Bunk <bunk () stusta ! de>
Date:       2005-01-31 19:01:54
Message-ID: 20050131190154.GB18316 () stusta ! de
[Download RAW message or body]

This patch contains the following possible cleanups:
- make some needlessly global code static
- ide-dma.c: remove the unneeded EXPORT_SYMBOL(__ide_dma_test_irq)

Signed-off-by: Adrian Bunk <bunk@stusta.de>
