Hi All,

Not sure if it has been reported, clang builds of arm64 allmodconfig have
failed to build next-20220818 with the error:

drivers/net/wireless/realtek/rtw88/main.c:731:2: error: variable 'primary_channel_idx' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
        default:
        ^~~~~~~
drivers/net/wireless/realtek/rtw88/main.c:754:39: note: uninitialized use occurs here
        hal->current_primary_channel_index = primary_channel_idx;
                                             ^~~~~~~~~~~~~~~~~~~

git bisect pointed to 341dd1f7de4c ("wifi: rtw88: add the update channel flow to support setting by parameters").
And, reverting that commit has fixed the build failure.

I will be happy to test any patch or provide any extra log if needed.
