From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Abraham Subject: [PATCH v2] of/irq: add empty irq_of_parse_and_map() for non-dt builds Date: Sun, 25 Mar 2012 20:32:49 +0530 Message-ID: <1332687769-3127-1-git-send-email-thomas.abraham@linaro.org> Return-path: Sender: linux-samsung-soc-owner@vger.kernel.org To: devicetree-discuss@lists.ozlabs.org, linux-kernel@vger.kernel.org Cc: rob.herring@calxeda.com, grant.likely@secretlab.ca, linux-samsung-soc@vger.kernel.org, patches@linaro.org List-Id: devicetree@vger.kernel.org Add a empty irq_of_parse_and_map() function that returns 0 for non-dt builds and avoid having #ifdef CONFIG_OF around all calls to irq_of_parse_and_map(). In addition to that, the irq_of_parse_and_map() function declaration is made available only if CONFIG_OF_IRQ is defined, which is the same config option that makes the irq_of_parse_and_map() function definition available. While at it, fix a typo as well.
