[PATCH 5.19 174/192] hwmon: (mr75203) update pvt->v_num and vm_num to the actual number of used sensors
From: Greg Kroah-Hartman
Date: Tue Sep 13 2022 - 10:25:07 EST
From: Eliav Farber <farbere@xxxxxxxxxx>
[ Upstream commit bb9195bd6664d94d71647631593e09f705ff5edd ]
This issue is relevant when "intel,vm-map" is set in device-tree, and
defines a lower number of VMs than actually supported.
This change is needed for all places that use pvt->v_num or vm_num
later on in the code.
