Subject: usb_ohci: Always use little endian
X-Git-Tag: v2.7.1~7830
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=34557491911f8977b5863628b1b6f5a9c95f9c29;p=mirror_qemu.git

usb_ohci: Always use little endian

This patch replaces explicit bswaps with endianness hints to the
mmio layer.

Because we don't depend on the target endianness anymore, we can also
move the driver over to Makefile.objs.
