[PATCH next] pinctrl: tegra: Fix off by one in tegra_pinctrl_get_group()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

This should be >= pmx->soc->ngroups instead of > to avoid an out of
bounds access.  The pmx->soc->groups[] array is allocated in
tegra_pinctrl_probe().

Fixes: c12bfa0fee65 ("pinctrl-tegra: Restore SFSEL bit when freeing pins")
