﻿Hmm. Doesn't compile for me in 2.6.25-rc2-git7:

CC [M] drivers/usb/host/u132-hcd.o
drivers/usb/host/u132-hcd.c: In function ‘u132_suspend’:
drivers/usb/host/u132-hcd.c:3224: error: expected expression before
‘int’
drivers/usb/host/u132-hcd.c:3225: error: ‘ports’ undeclared (first use
in this function)
drivers/usb/host/u132-hcd.c:3225: error: (Each undeclared identifier is
reported only once
drivers/usb/host/u132-hcd.c:3225: error: for each function it appears
in.)
make[3]: *** [drivers/usb/host/u132-hcd.o] Error 1
make[2]: *** [drivers/usb/host] Error 2
make[1]: *** [drivers/usb] Error 2
make: *** [drivers] Error 2

This fixes it:

Thanks
