If anyone has any objections, please let me know. ------------------ From: Abdun Nihaal [ Upstream commit 42754b7de2b1a2cf116c5e3f1e8e78392f4ed700 ] In mt76_wmac_probe(), when the mt76_alloc_device() call succeeds, memory is allocated for both struct ieee80211_hw and a workqueue. However, on the error path, the workqueue is not freed. Fix that by calling mt76_free_device() on the error path.
