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:
ath/ath10k/mac.c:839]: (error) Possible null pointer dereference: chandef
