From b28b08de436a638c82d0cf3dcdbdbad055baf1fc Mon Sep 17 00:00:00 2001 From: Jérôme Glisse Date: Tue, 10 Apr 2018 16:28:15 -0700 Subject: mm/hmm: fix header file if/else/endif maze The #if/#else/#endif for IS_ENABLED(CONFIG_HMM) were wrong. Because of this after multiple include there was multiple definition of both hmm_mm_init() and hmm_mm_destroy() leading to build failure if HMM was enabled (CONFIG_HMM set).
