Hello,
This cleans up some of the user code around calls to dev_pm_opp_of_remove_table().
All the patches can be picked by respective maintainers directly except for the last patch, which needs the previous two to get merged first.
These are based for 5.9-rc1.
Rajendra, Since most of these changes are related to qcom stuff, it would be great if you can give them a try. I wasn't able to test them due to lack of hardware.

dev_pm_opp_of_remove_table() doesn't report any errors when it fails to find the OPP table with error -ENODEV (i.e. OPP table not present for the device). And we can call dev_pm_opp_of_remove_table() unconditionally here.
