From 35d04077ad96ed33ceea2501f5a4f1eacda77218 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Fri, 7 Oct 2016 10:40:59 -0700 Subject: [PATCH] metag: Only define atomic_dec_if_positive conditionally The definition of atomic_dec_if_positive() assumes that atomic_sub_if_positive() exists, which is only the case if metag specific atomics are used. This results in the following build error when trying to build metag1_defconfig. kernel/ucount.c: In function 'dec_ucount': kernel/ucount.c:211: error: implicit declaration of function 'atomic_sub_if_positive' Moving the definition of atomic_dec_if_positive() into the metag conditional code fixes the problem.
