From: Bitterblue Smith <rtl8821cerfe2@xxxxxxxxx>
[ Upstream commit 6f103aeb5e985ac08f3a4a049a2c17294f40cff9 ]
The wifi + bluetooth combo chips (RTL8723AU and RTL8723BU) read the
chip vendor from the wrong register because the val32 variable gets
overwritten. Add one more variable to avoid this.
This had no real effect on RTL8723BU. It may have had an effect on
RTL8723AU.
Fixes: 26f1fad29ad9 ("New driver: rtl8xxxu (mac80211)")
