Subject: re: ath11k: initialize wmi config based on hw_params


static analysis with Coverity has detected a duplicated assignment issue
with the following commit:

commit 2d4bcbed5b7d53e19fc158885e7340b464b64507

    ath11k: initialize wmi config based on hw_params

The analysis is as follows:

 74        config->beacon_tx_offload_max_vdev = 0x2;
 75        config->num_multicast_filter_entries = 0x20;
 76        config->num_wow_filters = 0x16;

Unused value (UNUSED_VALUE)
assigned_value: Assigning value 1U to config->num_keep_alive_pattern
here, but that stored value is overwritten before it can be used.
 77        config->num_keep_alive_pattern = 0x1;

value_overwrite: Overwriting previous write to
config->num_keep_alive_pattern with value 0U.

 78        config->num_keep_alive_pattern = 0;

I'm not sure if one of these assignments is redundant, or perhaps one of
the assignments is meant to be setting a different structure element.
