Subject: Strange build error with new driver on 2.6.39-rc3

When building a new driver on kernel 2.6.39-rc3 when using a 32-bit system, I
get the following error:

MODPOST 511 modules
FATAL: drivers/net/wireless/rtlwifi/rtl8192se/rtl8192se: sizeof(struct
usb_device_id)=20 is not a modulo of the size of section __mod_usb_device_table=168.
Fix definition of struct usb_device_id in mod_devicetable.h

This error is strange in that this device is PCI based and contains no mention
of usb_device_id. There is a USB-based driver in the rtlwifi tree, but there is
also another PCI driver and it does not get this error.

Thanks,

Larry

I found the problem. It was a faulty MODULE_DEVICE_TABLE macro statement.
