[PATCH v1 09/11] arm_mpam: resctrl: Make read_mon_cdp_safe() self consistent

[Ben Horgan]

When read_mon_cdp_safe() is called with cdp_enabled equal to false then the
reading returned in val is the sum of the monitor values for the given
component. However, when cdp_enabled equal to true it is again the sum of
the monitor values but with the initial value of val also added.

Change the cdp_enabled equals true case to match the false case. All
callers zero the val before calling and so no functional change is
anticipated.
