From c122c5b68273cf0153d1dc510889728cf71e8ce3 Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Thu, 1 May 2014 11:50:16 -0700 Subject: 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.
