From c5782e9f5a535af09d7834693a52afdbcc6e5f3f Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Mon, 26 Nov 2012 16:29:38 -0800 Subject: [PATCH] include/linux/bug.h: fix sparse warning related to BUILD_BUG_ON_INVALID Commit baf05aa9271b ("bug: introduce BUILD_BUG_ON_INVALID() macro") introduces this macro only when _CHECKER_ is not defined.
