For aesthetics, rename this function so it has namespace associated
with the driver.

Change the parameters to the function. The 'mode' is really a flag to
load the counters and the divisors can be found in the private data.

To clarify the code and remove the magic numbers, use the 8253.h
helpers to set the timer mode and load the counters.

The local variable 'mode' is not necessary. We can determine the mode

When the cmd->convert_src == TRIG_TIMER the divisors needed to
generate the pacer time are calculated in the (*do_cmdtest) to
validate the cmd->convert_arg. The core always does the (*do_cmdtest)
before the (*do_cmd) so there is no reason to recalc the divisors.

Save the calculated divisors in the private data as 'next_divisor[12]'.
The (*do_cmd) then transfers them to the private data 'divisor[12]' so
that they can be used to set the timer for the command immediately or
later when the cmd->start_src is TRIG_EXT (mode 2 in this driver).

The chanlist is checked in Step 5 of the (*do_cmdtest) there is no
reason to check it again in the (*do_cmd). The only reason its done
again is to get the actual 'seglen', the non-repeating length of the

Save the 'seglen' found by pci171x_ai_check_chanlist() in the private

The obd_ioctl_getdata() function caps "data->ioc_len" at
OBD_MAX_IOCTL_BUFFER and then calls this obd_ioctl_is_invalid() to check
that the other values inside data are valid.

There are several lengths inside data but when they are added together
they must not be larger than "data->ioc_len".  The checks against
"(data->ioc_inllen1 > (1<<30))" are supposed to ensure that the addition
does not have an integer overflow.  But "(1<<30) * 4" actually can
overflow 32 bits, so the checks are insufficient.

I have changed it to "> OBD_MAX_IOCTL_BUFFER" instead.
