commit 97b9b3250904992e053fc930ab16277f354b1e42 Author: Andre Przywara <andre.przywara@xxxxxxx> AuthorDate: Fri Apr 7 11:23:53 2017 +0100 Commit: Stefano Stabellini <sstabellini@xxxxxxxxxx> CommitDate: Wed Jun 14 11:38:37 2017 -0700 ARM: GIC: export and extend vgic_init_pending_irq() For LPIs we later want to dynamically allocate struct pending_irqs. So beside needing to initialize the struct from there we also need to clean it up and re-initialize it later on. Export vgic_init_pending_irq() and extend it to be reusable.
