Sorry but this patch is neither serious nor acceptable. First of all,
hardcoding macpower like this right after an if statement is plain
wrong, second your comments violate all kernel rules.
Second, you argue this was tested using code test - on which device? Did
you test it on all rtl8xxxu based devices or just rtl8723bu?
NACK
