Subject: [PATCH 15/17] ARM: rpc: check device_register return code in ecard_probe
Date: Tue, 2 Oct 2012 18:36:54 +0200 [thread overview]
Message-ID: <1349195816-2225-16-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1349195816-2225-1-git-send-email-arnd@arndb.de>
device_register is marked __must_check, so we better propagate the error
value by returning it from ecard_probe.
Without this patch, building rpc_defconfig results in:
arch/arm/mach-rpc/ecard.c: In function 'ecard_probe':
arch/arm/mach-rpc/ecard.c:963:17: warning: ignoring return value of 'device_register', declared with attribute warn_unused_result [-Wunused-result]
