[PATCH V2 4/8] mmc: sdhci-msm: Unconditionally call dev_pm_opp_of_remove_table()

From: Viresh Kumar <viresh.kumar@linaro.org>
Date: 2020-08-28 06:09:03
Also in: linux-arm-msm, linux-mmc, lkml
Subsystem: arm/qualcomm mailing list, multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, the rest · Maintainers: Ulf Hansson, Adrian Hunter, Linus Torvalds

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.

Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>

V2:
- Compare with -ENODEV only for failures.
- Create new label to put clkname.
