[ Upstream commit 450edd2805982d14ed79733a82927d2857b27cac ]
Some devices like TP-Link TL-WN722N produces this kind of messages frequently.
kernel: ath: phy0: Short RX data len, dropping (dlen: 4)
This warning is useful for developers to recognize that the device (Wi-Fi dongle or USB hub etc) is noisy but not for general users. So this patch make this warning to debug message.
