Subject: [PATCH] au1xxx-ide.c: ioremap() returns a void __iomem *
The ioremap return value is an __iomem *, not an integer. Update the
private structure to reflect this. While here, remove the typedef
for _auide_hwif and just use struct auide_hwif instead as recommended
by Documentation/CodingStyle.
auide_setup_ports() still needs to cast the regbase back to an integer
to correctly setup the io_ports_array.
