+Subject: wifi: mt76: do not run mt76_unregister_device() on unregistered hw
+Origin: https://patchwork.kernel.org/project/linux-wireless/patch/be3457d82f4e44bb71a22b2b5db27b644a37b1e1.1677107277.git.lorenzo@kernel.org/
+Bug-Debian: https://bugs.debian.org/1029116
+
+Trying to probe a mt7921e pci card without firmware results in a
+successful probe where ieee80211_register_hw hasn't been called. When
+removing the driver, ieee802111_unregister_hw is called unconditionally
+leading to a kernel NULL pointer dereference.
+Fix the issue running mt76_unregister_device routine just for registered
+hw.

+
+Currently queued for review for the v6.3 release cycle, backported in
+advance to prevent users from getting stuck in the installer.
