Subject: staging: vt6656: don't return zero on failure path in vt6656_probe()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=20ff1418d3936f76df24f5694c6b5eb9179a565f;p=openwrt%2Fstaging%2Fblogic.git

staging: vt6656: don't return zero on failure path in vt6656_probe()

If ieee80211_alloc_hw() fails in vt6656_probe(), it breaks off
initialization, but returns zero.
