modules: mark __inittest/__exittest as __maybe_unused

arndb · Jessica Yu · commit 1f318a8bafcf · 2017-02-06T15:26:15.000-08:00
clang warns about unused inline functions by default:

arch/arm/crypto/aes-cipher-glue.c:68:1: warning: unused function '__inittest' [-Wunused-function]
arch/arm/crypto/aes-cipher-glue.c:69:1: warning: unused function '__exittest' [-Wunused-function]

As these appear in every single module, let's just disable the warnings by marking the
two functions as __maybe_unused.
