qca6174 hw2.1 firmware crash with kernel 4.1.2

[Enrico Tagliavini]

Mhm seems like I assumed the backport missing from 4.0 was merged for
4.1.... but it is not, it's in 4.2 only. Any chance you'll ask for a
backport of this 4 lines patch?

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/ath/ath10k?id=11a002efbaa7fbd9f6e616695ab42aa9f1caf060

Would be much appreciated
