Subject: soc/tegra: pmc: Remove additional check for a valid partition
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c3ea297260b77a99a2383c1029a381d125f788fe;p=linux-beck.git

soc/tegra: pmc: Remove additional check for a valid partition

The function tegra_powergate_is_powered() verifies that the partition
being queried is valid and so there is no need to check this before
calling tegra_powergate_is_powered() in powergate_show(). So remove this
extra check.
