Subject[PATCH 1/1] net: bcmgenet: fix incorrect return value checks
Date
From: Pan Bian <bianpan2016@163.com>

Function platform_get_irq() will return a negative value on errors.
However, in function bcmgenet_probe(), 0 is considered as a flag of
error. This patch fixes the bug by checking whether the return value of
platform_get_irq() is less than 0.
