Subject[PATCH 1/1] net: ethernet: 3com: set error code on failures
Date
From: Pan Bian <bianpan2016@163.com>

In function typhoon_init_one(), returns the value of variable err on
errors. However, on some error paths, variable err is not set to a
negative errno. This patch assigns "-EIO" to err on those paths.
