[PATCH 4.19 120/139] ASoC: pcm186x: Fix device reset-registers trigger value

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andreas Dannenberg <dannenberg@xxxxxx>

commit 5277715639ff6f75c729e657690751a831112c4b upstream.

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.
