Subject: [PATCH 5.7 074/265] ALSA: usb-audio: Set 48 kHz rate for Rodecaster

From: Christopher Swenson <swenson@...nson.io>

commit 8abf41dcd1bcdda0d09905fb59d18f45c035c752 upstream.

Like the Line6 devices, the Rode Rodecaster Pro does not support
UAC2_CS_RANGE and only supports a sample rate of 48 kHz.

Tested against a Rode Rodecaster Pro.
