}help!
when I call to io_devctl , just before leaving function check the data and I see that they are correct and when return of the function the data are not such, 
//in io_devctl …
if (IoControlCode == 0x88) // command GetCardVersion
{
t2 = (ADMXRC_IOCTLS_GETVERSIONINFO *) iop->out.lpBuffer ; //checking the info returned by fops_ioctl <— function
os_dbgprint(0, (“GetVersionInfo %d.%d\n”, t2->major, t2->minor) );
// all is correct 
print 3.6

the problem may be are in
SETIOV (ctp -> iov, &msg -> o, sizeof (msg->o) + nbytes);
return (_RESMGR_NPARTS (1));
//return ( _RESMGR_PTR(ctp, &msg->o, sizeof(msg->o)+nbytes) );
please tell me why no return with tha data correctly.
help!!!
