From 2a833a02a12b1dbb605739d589d11b4400c2078c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 25 Jul 2018 23:24:10 +0200 Subject: ALSA: echoaudio: Proper endian notations Many data fields defined in echoaudio drivers are in little-endian, hence they should be defined with __le16 or __le32. This makes it easier to catch the forgotten conversions.
