Thanks. This is always good to add to the commit log so I did that:

    ath10k: fix wrong initialization of struct channel
    
    chandef is initialized with NULL and on the very next line, we are using it to
    get channel, which is not correct. Channel should be initialized after
    obtaining chandef.
    
    Found by cppcheck:
