Before, we were using
while (*p++ && --len > 0);
to do this. However, len doesn't get decremented for the NUL byte, so when
we used len later to see if we still have CIS left for some optional fields,
we'd run off the end of an array and dump core.
Instead, replace it with
len -= strlen(p) + 1;
p += strlen(p) + 1;
which is more correct. It is a little bogus to assume that p points to
a valid C string, but only a little. The PC Card SPEC mandates that it
does, and we already depend on that with the use of strdup a few lines
earlier. Since much of the rest of the cis parsing code isn't hyper
retentive about error checking, I'll leave that level of checking for
another time and/or another committer :-).
the config file. This fixes the breakage caused by the recent change
in the behavior of device_add_child for ata (which shows soren's
reservations were well founded).

16 bits access is required by nsp driver to work in SMIT mode.
Since previously (1.65 and before in current, and 1.46.28 and before
in stable branch) 16 bits access was default, I hope it will break nothing.

on older kernels correctly. Terminate the loop when we find a
suitable irq. Also, only try to select from the pool. Cleaned up the
two cases (IRQ picked by the user and ?) into one.

use it. If not, then loop asking for each one, with normal -I
processing. This will effectively disable -I for when the pcic is in
PCI function interrupt routing mode.

allocate 0x138-0x198, for example).
Use err(1,"foo") rather than perror + exit while I'm here.
will soon return the irq from the pcic bridge in cases where't that's
appropriate.
Note: I've had to disbale -I option for the moment. I've made it easy
to reenable it for people that need it.

The PCCard daemon can hang indefinately while reading its
configuration file. If the last line of the file is a comment line
that does not end in a newline, the program goes into an infinite
loop searching for the non-existent newline.
This fix, provided by the PR, will allow files ending without a newline
to be read without hanging.

IRQs from kernel.''..
With IBM ThinkPad600. ``sio1'' was disabled in BIOS
and irq 3 was free (also not listed in dmesg), I think.
But I could not use irq 3 for PC-Card with new(PIOCSRESOURCE
ioctl enabled) pccardd.
- If resource which was allocated for pcic was
requested via this ioctl, bus_alloc_resource
would be succeeded and that resource was
returned as free resource. So check whether
requested resource was used for pcic or not
before bus_alloc_resource test.
- merge SYS_RES_IRQ routine into other SYS_RES_*
routine and clean up.
