Subject: mac80211: fix memory leak in device registration error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cfff2f999d9baa561f20d999c8b83b03f078fb8f;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

mac80211: fix memory leak in device registration error path

If the cipher suites need to be allocated, but this
allocation fails, this leaks the internal scan request.
Fix that by going to the correct error handling label.
