Subject: [PATCH] ASoC: pcm186x: Fix device reset-registers trigger value
Date:   Thu, 15 Nov 2018 11:01:31 -0600

According to the current device datasheet (TI Lit # SLAS831D, revised
March 2018) the value written to the device's PAGE register to trigger
a complete register reset should be 0xfe, not 0xff. So go ahead and
update to the correct value.
