https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/core commit aff62cf66ad6065ce04fc3454a11ec19714537fb Author: Daniel Lezcano <daniel.lezc...@linaro.org> AuthorDate: Thu Jan 14 10:54:13 2016 +0100 Commit: Thomas Gleixner <t...@linutronix.de> CommitDate: Mon Feb 8 11:45:21 2016 +0100 genirq: Use a common macro to go through the actions list The irq code browses the list of actions differently to inspect the element one by one. Even if it is not a problem, for the sake of consistent code, provide a macro similar to for_each_irq_desc in order to have the same loop to go through the actions list and use it in the code.
