Subject: [PATCH] ide: falconide/q40ide - Use __ide_mm_{in,out}sw() for data transfer
Date: Wed, 1 Apr 2009 22:43:50 +0200 (CEST) [thread overview]
Message-ID: <Pine.LNX.4.64.0904012243060.29342@anakin> (raw)
Both of commits f94116aeec7a299640dd692128e1d22178affa8d ("ide: cleanup
<asm-m68k/ide.h>") and 15a453a955f89f6545118770c669b52e925368bd ("ide: include
<asm/ide.h> only when needed") break falconide:
| Uniform Multi-Platform E-IDE driver
| ide: Falcon IDE controller
| Probing IDE interface ide0...
| hda: Sarge m68k, ATA DISK drive
| ide0 at 0xfff00000 on irq 15 (serialized)
| ide-gd driver 1.18
| hda: max request size: 128KiB
| hda: 2118816 sectors (1084 MB) w/256KiB Cache, CHS=2102/16/63
| hda:<4>hda: lost interrupt
This happens because falconide relies on {in,out}sw() being redefined in
<asm/ide.h>, as included by <linux/ide.h>, which is no longer the case.
Use __ide_mm_{in,out}sw() from <asm/ide.h> instead, just like
ide_{in,out}put_data() do.
The same problem seems to exist in q40ide.
