Hi Dan carpenter
Thanks for reporting issue. Could you please help in reproducing the
issue,
I tried to reproduce the warnings using command, but could not
make C=1 CHECK="smatch -p=kernel" -C.
drivers/net/wireless/ath/ath11k/ modules
My PC has,
gcc --version
gcc (Ubuntu 10.3.0-1ubuntu1~20.04) 10.3.0
sparse --version
v0.6.3-rc1
smatch --version
v0.5.0-7764-g0951ed59
Build LOGS:

I don't see why you need to reproduce the error. rx_buf_sz is
uninitialised as there's no else statement, like Dan mentioned above.
Anil, can you send a patch?
