thats true. but due the nature of this function i found it better to use 
nowait here. better if i split it up?

no? i use midnight commander for all of my code since more than 20 years
and its the first time that i see such warnings. is there any special 
coding rule for ath10k which differs from the kernel rules?
and where is ath10k-check located?
