Yesterdays kernel/git/kvalo/ath.git failes with COMPEX WLE600VX

[Joerg Pommnitz]

Kalle,
your patch did not really make a difference. ath10k now says:
[   13.098404] ath10k_pci 0000:05:00.0: BAR 0: assigned [mem 0x48400000-0x485fffff 64bit]
[   13.128788] ath10k_pci 0000:05:00.0: failed to wake up device : -110
[   13.146877] ath10k_pci: probe of 0000:05:00.0 failed with error -110

dmesg log is attached.
