ath9k_hw_reset() in ath9k_start() can fail, and in this case, 
ath9k_start() should return an error instead of executing the 
subsequent code.
Such mechanical patches w/o understanding the code are always
problematic. Do you have any proof that this error is fatal?
I think it is not, else we wouldn't have this line:
ah->reset_power_on = false;
Also you should consider that a mutex and a spinlock are held.
Maybe changing the error message to a warning would be more
appropriate. But this I would leave to somebody being more
familiar with this driver.
A very good point, thanks Heiner! I will drop this unless someone
familiar with ath9k says that this is ok.
