Hi, 

Recently while trying to figure out a separate issue, I did a
make allmodconfig and a make oldconfig with debian's default config on
the 3.10.1 kernel, and debian's config with 3.10.0.

It failed in the wil6210 driver.

The system it failed on is running a fresh install of Debian Sid, with gcc
4.8.1.

This is the error I got:

  CC [M]  drivers/net/wireless/ath/wil6210/debugfs.o

please excuse the mangled quotes, fresh install and I negelected to set up

notice.

This error should be fixed by the attached patch. Please test.

Note that my system did not issue a warning for this "problem". It seems we have 
different warnings turned on in the compiler.

The warnings have gone away, and the first error, but the second one is still 
there.

Sorry, I missed the second one in your original message. Does this one fix it?
