Subject: [PATCH] irqchip/gic-v5: Remove the redundant ITS cache invalidation
Date: Wed, 3 Sep 2025 10:33:19 +0800 [thread overview]
Message-ID: <20250903023319.1820-1-yuzenghui@huawei.com> (raw)
An ITS cache invalidation has been performed immediately after programming
the L2 DTE in gicv5_its_device_register(). No need to perform it again
right after a successful gicv5_its_device_register().
Remove it.
