Alexey Dobriyan noticed that the new WARN_ON() semantics that were
introduced by commit 684f978347 (to also
return the value to be warned on) didn't compile when given a bitfield,
because the typeof doesn't work for bitfields.
So instead of the typeof trick, use an "int" variable together with a
"!!(x)" expression, as suggested by Al Viro.
To make matters more interesting, Paul Mackerras points out that that is
sub-optimal on Power, but the old asm-coded comparison seems to be buggy
anyway on 32-bit Power if the conditional was 64-bit, so I think there
are more problems there.
Regardless, the new WARN_ON() semantics may have been a bad idea. But
this at least avoids the more serious complications.

This updates some error reporting paths in SPI device setup:
- Move validation logic for SPI chipselects to spi_new_device(),
which is where it should always have been.
- In spi_new_device(), emit error messages if the device can't
be created. This is LOTS better than a silent failure; though
eventually, the calling convention should probably change to
use the <linux/err.h> conventions.
- Includes one previously-missing check: SPI masters must always
have at least one chipselect, even for dedicated busses which
always keep it selected!
It also adds a FIXME (IDR for dynamic ID allocation) so the issue doesn't live
purely in my mailbox.

This patch fix weird behaviour of UDF mounting procedure. To get UID
changed (for now) we have to type
mount -t udf -o uid=some_user,uid=ignore /dev/device /mnt/moun_point

able to mount without additional 'uid=ignore' option. The same for GID
option is done.

Coverity spotted what looks like a real possible case of using a variable
after it has been freed. The problem is in
kernel/relay.c::relay_open_buf()
If the code hits "goto free_buf;" it ends up in this code :
free_buf:
relay_destroy_buf(buf); <--- calls kfree() on 'buf'.
free_name:
kfree(tmpname);
end:
return buf; <-- use after free of 'buf'.
I read through the callers and they all handle a NULL return from this
function as an error (and hitting the 'free_buf' label only happens on
failure to chan->cb->create_buf_file(), so that looks like a clear error to
me).
The patch simply sets 'buf' to NULL after the call to
relay_destroy_buf(buf); - as far as I can see that should take care of the
problem.
The patch also corrects a reference to a documentation file while
I was at it.
Note from Mathieu: the documentation reference change should have been
done in a separate patch, but I guess no one will really care.

This is only called at init time and only happens if the BIOS screws
something up, so the leak is slight and it is probably not worth sending to
2.6.22.x. The driver would not initialize the interface in the case, and I
have no reports of this happening. I have booted and run tests on a system
with this patch. Note that the original patch was munged by the mailer,
here's a new one.
If we ever hit the "default:" case in the switch in try_init_dmi(),
then we'll leak the storage allocated with kzalloc() and assigned
to 'info'.
