+From: b.sander
+Subject: [PATCH] pci: IDE fix
+
+These are standard probing messages when using pdc202xx_old:
+pdc202xx_old 0000:00:01.0: IDE controller (0x105a:0x0d30 rev 0x02)
+PCI: Enabling device 0000:00:01.0 (0004 -> 0007)
+PCI: Fixing up device 0000:00:01.0
+0000:00:01.0: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.
+0000:00:01.0: FORCING BURST BIT 0x00->0x01 ACTIVE
+pdc202xx_old 0000:00:01.0: 100% native mode on irq 6
+
+With the default MAX_HWIFS value after above we get:
+ ide2: BM-DMA at 0x0400-0x0407
+ ide3: BM-DMA at 0x0408-0x040f
+Probing IDE interface ide2...
+hde: CF500, CFA DISK drive
+
+As you can see it's ide2 + ide3 and hde.
+
+With this patch applied we get:
+ ide0: BM-DMA at 0x0400-0x0407
+ ide1: BM-DMA at 0x0408-0x040f
+Probing IDE interface ide0...
+hda: CF500, CFA DISK drive
+
+This fixes OpenWrt ticket #7061: https://dev.openwrt.org/ticket/7061
