Subject: [PATCH 9/9] ARM: mmp: mark usb_dma_mask as __maybe_unused
Date: Fri, 29 Jan 2016 15:06:33 +0100 [thread overview]
Message-ID: <1454076396-3563101-10-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1454076396-3563101-1-git-send-email-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.
