Subject: [PATCH 4.9 033/102] cfg80211: fix memory leak of wiphy device name

From: Eric Biggers <>

commit 4f488fbca2a86cc7714a128952eead92cac279ab upstream.

In wiphy_new_nm(), if an error occurs after dev_set_name() and
device_initialize() have already been called, it's necessary to call
put_device() (via wiphy_free()) to avoid a memory leak.

Fixes: 1f87f7d3a3b4 ("cfg80211: add rfkill support")
