linux-next: build warning after merge of the drivers-x86 tree

[Stephen Rothwell]

Hi Darren,

After merging the drivers-x86 tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from include/linux/kernel.h:13:0,
                 from drivers/platform/x86/thinkpad_acpi.c:52:
drivers/platform/x86/thinkpad_acpi.c: In function 'hotkey_init':

  ^

  char *type;

Introduced by commit

  b31800283868 ("platform/x86: thinkpad_acpi: Move tablet detection into separate function")

I can't tell if this is a false positive or not.
