Subject: [PATCH] sfp: Fix error handing in sfp_probe()
Date: Sat, 31 Oct 2020 11:10:53 +0800 [thread overview]
Message-ID: <20201031031053.25264-1-yuehaibing@huawei.com> (raw)
gpiod_to_irq() never return 0, but returns negative in
case of error, check it and set gpio_irq to 0.
Fixes: 73970055450e ("sfp: add SFP module support")
