[PATCH 0/3] ath10k: fix host corruption

This patchset aims at fixing (or at least
reducing) the frequency of a (apparently) strange
HW bug.

The bug happens in some workloads with different
frequency with different hardware spinoffs. It is
triggered by a cold reset after HW/FW has been
excercised with some work.

On x86 this could be a hang, on AP135 it is a data
bus error.

Michal Kazior (3):
  ath10k: fix device initialization routine
  ath10k: zero device DRAM to avoid host hangs
  ath10k: zero CE config upon deinit
