Right. I found it weird as well. Basically "ath10k_coredump" and
"ath10k_debug" operations are swapped between ath10k_core_create() and
ath10k_core_destroy().

If you wish, I can submit a patch ordering it properly.

Right. It is done in-between the workqueues and the coredump/debug
creation/destroy.

Thanks for the review.
