Subject: [PATCH] avoid releasing twice the same region on ide_release_iomio_dma()
Date: Mon, 24 Jul 2006 16:30:31 -0300	[thread overview]
Message-ID: <20060724193031.GA18463@cathedrallabs.org> (raw)

In ide_release_iomio_dma() it's possible to release twice
hwif->dma_base if hwif->dma_base2 is not null and never releasing
hwif->dma_base2:
int ide_release_iomio_dma (ide_hwif_t *hwif)
{
        if ((hwif->dma_extra) && (hwif->channel == 0))
                release_region((hwif->dma_base + 16), hwif->dma_extra);
        release_region(hwif->dma_base, 8);
        if (hwif->dma_base2)
                release_region(hwif->dma_base, 8);
                                     ^^^^^^^^^
        return 1;
}
This patch fixes this typo.
