With this patch applied the following waring shows up:

make --silent --keep-going --jobs=32
O=/home/anders/.cache/tuxmake/builds/current ARCH=arm64
CROSS_COMPILE=aarch64-linux-gnu-
                                drivers/soc/tegra/pmc.c: In function
'tegra_powergate_power_up':
drivers/soc/tegra/pmc.c:726:1: warning: label 'powergate_off' defined
but not used [-Wunused-label]   726 | powergate_off:
        | ^~~~~~~~~~~~~

If I cherry pick 19221e308302 ("soc/tegra: pmc: Fix imbalanced clock
disabling in error code path")
the wraning goes away.

Cheers,
Anders
