These should be gone in next already.

Best regards,

Hmm, which next?

I tried linux-next [1] from today (next-20120803, 55fa9961f) and still get

...
  CC      drivers/mtd/nand/mxc_nand.o

Sorry if I missed something ;)

next-20120725 contained 98d7bbb9929bcc14e11ac8a55245a4f2dc174e17, don't
konw why it isn't included in the newer next snapshorts.

First, yes, it was part of next-20120725. Second, I can confirm that 
the patch [1] fixes the compiler warnings I reported above. So my 
patch is obsolete now.

And third, strange is the absence in next-20120803 and 3.6-rc1. Do we 
a chance to find out what's ongoing here? It would be a shame if your 
patch get lost.

Many thanks

Dirk

It seems to be in -next again:

http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commit;h=98d7bbb9929bcc14e11ac8a55245a4f2dc174e17

I'm not so familiar with -next: Do we have any chance to get that 
commit into 3.6-rcX to get this warning fixed for the final 3.6?

Best regards

Dirk

Arnd sent a pull request that Linus T. seems to have ignored so far.
