From 4ebf83c8cf89ab13bc23e46b0fcb6178ca23b43c Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Mon, 9 Jul 2007 11:33:14 -0700 Subject: [PATCH] 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(...)
