[PATCH 0/8] opp: Unconditionally call dev_pm_opp_of_remove_table()

[PATCH 0/8] opp: Unconditionally call dev_pm_opp_of_remove_table()

[Viresh Kumar]

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.

[PATCH 1/8] cpufreq: imx6q: Unconditionally call dev_pm_opp_of_remove_table()

[Viresh Kumar]

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.
