You can also remove the test for padapter being NULL in this function,
as you just proved it could never be null otherwise the above function
you removed would have crashed, right? You should do that all at once
so we remember why that test was removed.
thanks,

Yes, padapter was deference without checking it could be NULL on rtw_resume.
I think having NULL check would be safe. However if padapter is NULL
then on goto exit "if (pwrpriv)" condition will never true as pwrpriv
is initialized with NULL. There should be one more goto exit just to
return.!
let me know you thought greg,
