From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] ssb: mark ssb_bus_register as __maybe_unused Date: Tue, 03 Nov 2015 16:05:51 +0100 Message-ID: <5928552.0ccybX7Zly@wuerfel> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Cc: Michael Buesch , linux-kernel@vger.kernel.org, zajec5@gmail.com, Nicolas Ferre , Alexandre Belloni , Jean-Christophe Plagniol-Villard To: netdev@vger.kernel.org, Kalle Valo Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The SoC variant of the ssb code is now optional like the other ones, which means we can build the framwork without any front-end, but that results in a warning: drivers/ssb/main.c:616:12: warning: 'ssb_bus_register' defined but not used [-Wunused-function] This annotates the ssb_bus_register function as __maybe_unused to shut up the warning. A configuration like this will not work on any hardware of course, but we still want this to silently build without warnings if the configuration is allowed in the first place. Signed-off-by: Arnd Bergmann Fixes: 845da6e58e19 ("ssb: add Kconfig entry for compiling SoC related code") ---- This showed up on ARM at91_defconfig and sama5_defconfig, so we should probably change those configurations as well. I can't see why they enable CONFIG_SSB when they do not use any drivers for this framework. diff --git a/drivers/ssb/main.c b/drivers/ssb/main.c index 5d1e9a0fc389..e2ff6b5b2094 100644 --- a/drivers/ssb/main.c +++ b/drivers/ssb/main.c @@ -613,9 +613,10 @@ out: return err; } -static int ssb_bus_register(struct ssb_bus *bus, - ssb_invariants_func_t get_invariants, - unsigned long baseaddr) +static int __maybe_unused +ssb_bus_register(struct ssb_bus *bus, + ssb_invariants_func_t get_invariants, + unsigned long baseaddr) { int err;
