2021-10-26irq: remove handle_domain_{irq,nmi}()Mark Rutland
Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

2017-08-23irqchip: Convert to using %pOF instead of full_nameRob Herring
Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

2017-07-18irqchip/digicolor: Drop unnecessary staticJulia Lawall
Drop static on a local variable, when the variable is initialized before any possible use. Thus, the static has no benefit. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Baruch Siach <baruch@tkos.co.il> Cc: keescook@chromium.org Cc: Marc Zyngier <marc.zyngier@arm.com> Cc: kernel-janitors@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org Cc: Jason Cooper <jason@lakedaemon.net> Link: http://lkml.kernel.org/r/1500149266-32357-11-git-send-email-Julia.Lawall@lip6.fr
2015-07-11irqchip: Prepare for local stub header removalJoel Porquet
The IRQCHIP_DECLARE macro moved to to 'include/linux/irqchip.h', so the local irqchip.h became an empty shell, which solely includes include/linux/irqchip.h Include the global header in all irqchip drivers instead of the local header, so we can remove it.
