Kees,

You can try the following.

Cool! Yeah, this finds the example:

drivers/comedi/drivers/rti800.c:74: struct comedi_lrange: field at offset 0 is the counter for the flex array
drivers/comedi/drivers/rti800.c:83: struct comedi_lrange: field at offset 0 is the counter for the flex array
drivers/comedi/drivers/rti800.c:92: struct comedi_lrange: field at offset 0 is the counter for the flex array

I'll run it on the whole codebase...

It found only the struct comedi_lrange instances, but that's good to
know. :)


Hi,

(removing most of people from the thread)


I found another one.

struct ocotp_devtype_data has a field 'num_entry' which is the number of entries in 'entry' flex array.
