Subject: wil6210 driver compilation failure

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
the locale properly. It's fixed now, but it seems I need to restart X for it to
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.

That seems to have done the trick.

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

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