6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thadeu Lima de Souza Cascardo <cascardo@xxxxxxxxxx>
[ Upstream commit 00260350aed80c002df270c805ca443ec9a719a6 ]
If ieee80211_register_hw fails, the memory allocated for the firmware will
not be released. Call deinit_sw_vars as the function that undoes the
allocationes done by init_sw_vars.
Fixes: cefe3dfdb9f5 ("rtl8192cu: Call ieee80211_register_hw from rtl_usb_probe")
