[PATCH 12/12] ipc/util.c: update return value of ipc_getref from int to bool

From: Manfred Spraul
Date: Thu Jul 12 2018 - 14:53:22 EST


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.
