Subject: soc/tegra: Fix an error handling path in tegra_powergate_power_up()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=986b5094708e508baa452a23ffe809870934a7df;p=linux.git

soc/tegra: Fix an error handling path in tegra_powergate_power_up()

If an error occurs after a successful tegra_powergate_enable_clocks()
call, it must be undone by a tegra_powergate_disable_clocks() call, as
already done in the below and above error handling paths of this function.

Update the 'goto' to branch at the correct place of the error handling
path.
