From 8b47038e6d349cca950e75076566a0de990c4645 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Thu, 21 Jun 2018 13:13:05 +0100 Subject: atomics/treewide: Remove redundant atomic_inc_not_zero() definitions When atomic_inc_not_zero(v) isn't defined, will define it as falling back to atomic_add_unless((v), 1, 0), so there's no need for arch code to do so. There should be no functional change as a result of this patch.
