Subject: [PATCH] irqchip/irq-bcm7120-l2: add put_device() after of_find_device_by_node()
Date: Tue, 9 Nov 2021 03:29:43 +0000 [thread overview]
Message-ID: <20211109032943.129855-1-ye.guojin@zte.com.cn> (raw)
From: Ye Guojin <ye.guojin@zte.com.cn>
This was found by coccicheck:
./drivers/irqchip/irq-bcm7120-l2.c,328,1-7,ERROR missing put_device;
call of_find_device_by_node on line 234, but without a corresponding
object release within this function.
./drivers/irqchip/irq-bcm7120-l2.c,341,1-7,ERROR missing put_device;
call of_find_device_by_node on line 234, but without a corresponding
object release within this function.
Addtionally, fixup the potential problem that memory is not released
before return.
