The following commit has been merged into the irq/core branch of tip: Commit-ID: 382d2ffe86efb1e2fa803d2cf17e5bfc34e574f3 Gitweb: https://git.kernel.org/tip/382d2ffe86efb1e2fa803d2cf17e5bfc34e574f3 Author: Guanrui Huang <guanrui.huang@xxxxxxxxxxxxxxxxx> AuthorDate: Thu, 18 Apr 2024 14:10:53 +08:00 Committer: Thomas Gleixner <tglx@xxxxxxxxxxxxx> CommitterDate: Thu, 25 Apr 2024 14:38:24 +02:00 irqchip/gic-v3-its: Remove BUG_ON in its_vpe_irq_domain_alloc This BUG_ON() is useless, because the same effect will be obtained by letting the code run its course and vm being dereferenced, triggering an exception. So just remove this check.
