Subject: [PATCH 05/12] ARM: mmp: mark usb_dma_mask as __maybe_unused
Date: Thu, 20 Jul 2017 17:51:43 +0200 [thread overview]
Message-ID: <20170720155209.3250880-2-arnd@arndb.de> (raw)
In-Reply-To: <20170720154616.3250481-1-arnd@arndb.de>
This variable may be used by some devices that each have their
on Kconfig symbol, or by none of them, and that causes a build
warning:
arch/arm/mach-mmp/devices.c:241:12: error: 'usb_dma_mask' defined but not used [-Werror=unused-variable]
Marking it __maybe_unused avoids the warning.
