Yes, that fixed it, tested on the panda-es. I'll send a patch through
in a moment.

I think that
struct omap_wdt_dev *wdev = watchdog_get_drvdata(wdog);
in omap_wdt_get_timeleft() needs to be
struct omap_wdt_dev *wdev = to_omap_wdt_dev(wdog);
Looks like there was an overlap between commit d2f78268ba58 ("watchdog:
omap: put struct watchdog_device into driver data") and commit 452fafed839e
("watchdog: omap_wdt: implement get_timeleft").
Can someone test this and send a patch to fix the problem ?
Thanks,

null pointer dereference in omap_wdt
Hi Lars, I'm seeing the following crash in omap_wdt in omap_wdt_get_timeleft when I just run wdctl on a couple of different TI devices, the beaglebone black/green or panda ES. I'm seeing it on both 4.2.3 and 4.3rc7, looking at git it looks like you added the fuction in June, have you seen this on any of your platforms?
