      ath9k: check ah->curchan when updating tx power · b01c9e32
      Stanislaw Gruszka authored
      When driver fail to reset card ah->curchan value stay NULL. When
      later driver try to update tx power it oops by using ah->curchan
      (calltrace is shown below).
      
      This problem were reported at various places and for some it was
      fixed by making ath9k_hw_chip_reset() do not fail. I have this bug
      report on some oldish RHEL kernel with AR9285, however it's hard to
      debug where reset fail when kernel OOPS, so I think this patch
      should be applied. Hopefully ah->curchan is not used unconditionally
      on other places until is initialized on ath9k_config().
