From 382d2ffe86efb1e2fa803d2cf17e5bfc34e574f3 Mon Sep 17 00:00:00 2001 From: Guanrui Huang Date: Thu, 18 Apr 2024 14:10:53 +0800 Subject: 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.
