4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andreas Dannenberg <dannenberg@ti.com>
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.
