Subject: [PATCH v4 02/14] irqchip/csky-apb-intc: Fix potential resource leaks
Date: Wed, 1 Jul 2020 10:16:14 +0800 [thread overview]
Message-ID: <1593569786-11500-3-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1593569786-11500-1-git-send-email-yangtiezhu@loongson.cn>
In the function ck_intc_init_comm(), system resources "reg_base" and
"root_domain" were not released in a few error cases. Thus add jump
targets for the completion of the desired exception handling.
Fixes: edff1b4835b7 ("irqchip: add C-SKY APB bus interrupt controller")
