From ac34df733d2dfe3b553897a1e9e1a44414f09834 Mon Sep 17 00:00:00 2001 From: "Geoffrey D. Bennett" Date: Wed, 23 Jun 2021 02:34:09 +0930 Subject: ALSA: usb-audio: scarlett2: Update get_config to do endian conversion For configuration items with a size of 16, scarlett2_usb_get_config() was filling *buf with little-endian data. Update it to convert to CPU endian. This function is not currently used so affects nothing yet; will be used by the upcoming talkback feature. Signed-off-by: Geoffrey D.
