ACPI: fix empty macros found by -Wextra
ACPI has a ton of macros which make a bunch of empty if's when configured in non-debug mode. [lenb: The code it complaines about is functionally correct, so this patch is just to make -Wextra happier] #define DBG() if(...) DBG(); next_c_statement which turns into if(...) ; next_c_statement Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
