If anyone has any objections, please let me know. ------------------ From: Haotian Zhang [ Upstream commit b4b1bd1f330fdd13706382be6c90ce9f58cee3f5 ] If devm_request_threaded_irq() fails after irq_domain_create_linear() succeeds in mt6397_irq_init(), the function returns without removing the created IRQ domain, leading to a resource leak. Call irq_domain_remove() in the error path after a successful irq_domain_create_linear() to properly release the IRQ domain.
