I believe this is related to the calibration data being provided in external files (dumped from the ART mtd partition at init time) rather than directly from the pcie board.  The patch and related discussion is from here: http://lists.infradead.org/pipermail/ath10k/2015-November/006489.html.  This has also been discussed a bit further on the ath10k list here: http://lists.infradead.org/pipermail/ath10k/2015-December/006613.html.

delete the line or not. but don't turn it into a comment. also the patch
needs mac80211 as a prefix rather than ath10k:
