From 2a9d6481004215da8e93edb588cf448f2af80303 Mon Sep 17 00:00:00 2001 From: Manfred Spraul Date: Tue, 21 Aug 2018 22:02:04 -0700 Subject: ipc/util.c: update return value of ipc_getref from int to bool ipc_getref has still a return value of type "int", matching the atomic_t interface of atomic_inc_not_zero()/atomic_add_unless(). ipc_getref now uses refcount_inc_not_zero, which has a return value of type "bool". Therefore, update the return code to avoid implicit conversions.
