   8 commit 6be3b6cce1e225f189b68b4e84fc711d19b4277b upstream.
   9
  10 In the 'commit ebee76f7fa46 ("ath10k: allow setting coverage class")',
  11 it inherits the design and the address offset from ath9k, but the address
  12 is not applicable to QCA6174, which leads to a random crash while doing the
  13 resume() operation, since the set_coverage_class.ops will be called from
  14 ieee80211_reconfig() when resume() (if the wow is not configured).
  15
  16 Fix the incorrect address offset here to avoid the random crash.
  17
  18 Verified on QCA6174/hw3.0 with firmware WLAN.RM.4.4-00022-QCARMSWPZ-2.
  19
  20 kvalo: this also seems to fix a regression with firmware restart.
