Subject: [ALSA] usb-audio - use bDeviceSubClass to detect MOTU FastLane
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bbd4615cdb68de943b2814e956ec14899606dc45;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[ALSA] usb-audio - use bDeviceSubClass to detect MOTU FastLane

USB generic driver
MOTU builds other USB MIDI interfaces with the same product ID as the
FastLane, so we have to check the bDeviceSubClass field to differentiate
between them.
