Subject: [PATCH] wifi: rtw88: 8821cu: Fix connection failure
Date: Sat, 23 Mar 2024 18:18:07 +0200 [thread overview]

[ Upstream commit 605d7c0b05eecb985273b1647070497142c470d3 ]
Clear bit 8 of REG_SYS_STATUS1 after MAC power on.
Without this, some RTL8821CU and RTL8811CU cannot connect to any
network:
Feb 19 13:33:11 ideapad2 kernel: wlp3s0f3u2: send auth to
90:55:de:__:__:__ (try 1/3)
Feb 19 13:33:13 ideapad2 kernel: wlp3s0f3u2: send auth to
90:55:de:__:__:__ (try 2/3)
Feb 19 13:33:14 ideapad2 kernel: wlp3s0f3u2: send auth to
90:55:de:__:__:__ (try 3/3)
Feb 19 13:33:15 ideapad2 kernel: wlp3s0f3u2: authentication with
90:55:de:__:__:__ timed out
The RTL8822CU and RTL8822BU out-of-tree drivers do this as well, so do
it for all three types of chips.
Tested with RTL8811CU (Tenda U9 V2.0).
