The pas16 and t128 drivers were removed (see 4.9/scsi-queue). The DMX3191
isn't an ISA card, so it isn't relevant.

I didn't find anything useful at that url.

Therefore, please change the help text as follows:

To compile this driver as a module, choose M here: the
module will be called g_NCR5380.


The rest of the patch looks good (aside from the missing module alias that
Chrisoph mentioned).

Thanks.
