There is currently no way to know if hotplug couldn't be called at all
or if it failed because it didn't have firmware load support.
If that happens, we would be waiting for ever. And I'd rather make that
a countable number of seconds :)
I'll make '0' mean no timeout at all.

That was the quickest way to get modules to play with :-)
I am not sure on how to implement "if a driver that uses it is
selected" and not sure on where to add the Kconfig entries to make it
available to out-of-kernel modules.
If the approach in the attached patches is still not right, please
complain.
Maybe kbuild could allow forcing one option from another, a companion
for 'depends', lets call it 'hard_depends'
depends FOO
If FOO is not there the entry won't even be shown in the
menu.
hard_depends FOO
FOO gets set to satisfy the dependency.
When trying to deselect an item that is hard_depended upon, the system
could complain and tell you which options should be deselected or even
offer to do it automatically.
This would also simplify the selection of crc32 and
compression/decompression code. And allow removal of all those comments
like "Video4Linux support is needed for USB Multimedia device support".

Since they are bit fields, I wanted to have more control over them and a
single bit bit-field should be unsigned, but I guess that David is
right, it is not worth it. Both are full int's now.

Fixed, and just in case, I put it through Lindent which BTW is a little
evil :-) so I hand removed the evilness I could not take.

Great.
Patches:
firmware-class.diff:
The code itself against bk-cvs.
class-casts.diff:
to_class_dev/to_class_dev_attr changes against bk-cvs.
sysfs-bin-header.diff
sysfs-bin-lost-dget.diff
sysfs-bin-flexible-size.diff:
Just for completeness, since the above will not work
without them, but I already send them to Pat Mochel in a
separate mail.
incremental.diff:
Incremental patch for easier reading, although there are
lots of formating changes.
Thanks
Manuel
PS: Sorry, I forgot the patches last time :(
PS2: Now that I really include the patches I realized their size, and
compressed some.
