From 6d6165603e162e3d391f35853a4ab232ab0db064 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 26 Apr 2019 16:56:03 +0200 Subject: amba: tegra-ahb: Mark PM functions as __maybe_unused clang warns about an unused variable when CONFIG_PM is disabled, since it is only referenced from an #ifdef: drivers/amba/tegra-ahb.c:97:18: error: variable 'tegra_ahb_gizmo' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration] Rather than trying to get the #ifdef right, remove it and use __maybe_unused here, which is less error prone.
