Subject: [PATCH v2] gpio: nuvoton: Fix sgpio irq handle error
Date: Mon, 29 Apr 2024 14:06:42 +0800 [thread overview]
Message-ID: <20240429060642.2920266-1-JJLIU0@nuvoton.com> (raw)
User use gpiomon to monitor input pin ,if triger the system will call trace and rcu stall.
The irq_handler uses generic_handle_domain_irq, so there is need to remove irq_find_mapping.
Fixes: c4f8457d17ce ("gpio: nuvoton: Add Nuvoton NPCM sgpio driver")
