2.6.16 compile error with latest cvs mtd source

Hello,

i have a problem compiling the 2.6.16 kernel for my csb637 board. I think this is an mtd related question because it works without patching the kernel against the mtd source code.

I have gcc 3.4.4 and binutils 2.16 and glibx 2.3.5.

The first step was compiling the 2.6.16 kernel without patching against the mtd cvs sources. --> The compilation was successfull.

But patching the kernel against the head of the mtd cvs repo resulted in the following warnings and errors:

(I used the command 'patchkernel.sh -2cyv $KERNELDIR' for patching)

Are there any suggestions?

Note: I patched the 2.6.15 kernel against the head of the mtd cvs repo which resulted in a successfully compilation.

Did you enable CONFIG_OBSOLETE_INTERMODULE in your .config? That was added in the 2.6.16 kernel because the inter_module stuff should really go away sometime.

Alternatively, the MTD subsystem should also probably select that Kconfig option so users don't see this. But MTD needs a sync anyway.
