From 5aecc243776e89b0c462edd0a589030baba99ef8 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Wed, 20 Oct 2021 15:49:03 +0100 Subject: [PATCH] irq: remove CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY Now that all users of CONFIG_HANDLE_DOMAIN_IRQ perform the irq entry work themselves, we can remove the legacy CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY behaviour.
