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

From: Viresh Kumar
Date: Thu Aug 20 2020 - 06:46:55 EST


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.
