+Subject: ALSA: usb-audio: Apply sample rate quirk for Audioengine D1
+
+From: Arvind Sankar <nivedita@alum.mit.edu>
+
+commit 93f9d1a4ac5930654c17412e3911b46ece73755a upstream.
+
+The Audioengine D1 (0x2912:0x30c8) does support reading the sample rate,
+but it returns the rate in byte-reversed order.
+
+When setting sampling rate, the driver produces these warning messages:
+[168840.944226] usb 3-2.2: current rate 4500480 is different from the runtime rate 44100
+[168854.930414] usb 3-2.2: current rate 8436480 is different from the runtime rate 48000
+[168905.185825] usb 3-2.1.2: current rate 30465 is different from the runtime rate 96000
+
+As can be seen from the hexadecimal conversion, the current rate read
+back is byte-reversed from the rate that was set.
+
+44100 == 0x00ac44, 4500480 == 0x44ac00
+48000 == 0x00bb80, 8436480 == 0x80bb00
+96000 == 0x017700, 30465 == 0x007701
+
+Rather than implementing a new quirk to reverse the order, just skip
+checking the rate to avoid spamming the log.
