regulator: tps65090: Fix tps65090 crash on Tegra Dalmore
The patch (60e91b5 regulator: tps65090: Allow setting the overcurrent wait time) introduced a crash on Tegra Dalmore. On Dalmore the device tree doesn't have an entry for all of the FETs so it leaves tps_pdata NULL in some cases. Add a check for NULL like the rest of the code does.
