From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kyle McMartin Subject: [PATCH] tegra-cpuidle: provide stub when !CONFIG_CPU_IDLE Date: Mon, 26 Aug 2013 11:30:51 -0400 Message-ID: <20130826153050.GC8764@redacted.bos.redhat.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-tegra-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-tegra-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-tegra@vger.kernel.org While poking at something using the for-3.12/* trees, I hit the following compile error: drivers/built-in.o: In function `tegra_pcie_map_irq': /builddir/build/BUILD/kernel-3.10.fc20/linux-3.11.0-0.rc6.git4.1.fc20.armv7hl/drivers/pci/host/pci-tegra.c:640: undefined reference to `tegra_cpuidle_pcie_irqs_in_use' drivers/built-in.o: In function `tegra_msi_map': /builddir/build/BUILD/kernel-3.10.fc20/linux-3.11.0-0.rc6.git4.1.fc20.armv7hl/drivers/pci/host/pci-tegra.c:1227: undefined reference to `tegra_cpuidle_pcie_irqs_in_use' make: *** [vmlinux] Error 1 Since our .config had CONFIG_CPU_IDLE off. We should probably provide an empty function to handle this to avoid cluttering up pci-tegra.c with conditionals.
