[PATCH] platform/x86: dell-wmi-sysman: Change user experience when Admin/System Password is modified

From: Prasanth KSR
Date: Mon Jun 28 2021 - 04:49:50 EST


Whenever user has changed an Admin/System Password using the sysfs,
then we are automatically copying the new password to existing
password field.
