When a TD length mismatch is found during isoc TRB enqueue, it directly
returns -EINVAL. However, isoc transfer is partially enqueued at this time,
and the ring should be cleared.

This should be backported to kernels as old as 2.6.36, which contain the

The probe does not strictly require the USB_CDC_DMM_TYPE
descriptor, which is a good thing as it makes the driver
usable on non-conforming interfaces.  A user could e.g.
bind to it to a CDC ECM interface by using the new_id and
bind sysfs files.  But this would fail with a 0 buffer length
due to the missing descriptor.

Fix by defining a reasonable fallback size: The minimum
device receive buffer size required by the CDC WMC standard,

This patch (as1515) fixes some unavoidably dumb compiler warnings:

  CC [M]  drivers/usb/renesas_usbhs/mod.o
In file included from drivers/usb/host/ohci-hcd.c:101:0:
drivers/usb/host/ohci-dbg.c: In function ‘fill_registers_buffer’:
drivers/usb/host/ohci-dbg.c:656:2: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]
drivers/usb/host/ohci-dbg.c:675:3: warning: the comparison will always evaluate as ‘true’ for the address of ‘next’ will never be NULL [-Waddress]

Instead of trying to fix the macro to work under all cirumstances,
just add a second macro for use in cases where the "next" argument is
the address of a local variable.

Unfortunately the macro cannot be replaced by a real subroutine,
because there's no va_list version of ohci_dbg() or dev_dbg().
