Hi Alan, with v3.8-rc3, ehci-hcd fails to compile for ARM if I use allmodconfig: drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition drivers/usb/host/ehci-mxc.c:280:31: warning: 'ehci_mxc_driver' defined but not used [-Wunused-variable] drivers/usb/host/ehci-hcd.c:1285:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1255:0: note: this is the location of the previous definition Looks like the recent ARM multi-arch patches didn't take into account EHCI-hcd. Now it becomes easy to see why giving ehci its own platform_device/driver would've been a lot easier ;-) -- balbi
