In the Linux kernel, the following vulnerability has been resolved:
watchdog: msc313e: Fix NULL pointer dereference in PM callbacks
msc313e_wdt_probe() doesn't set the driver data for the platform device.
As a result, dev_get_drvdata() in msc313e_wdt_suspend() and
msc313e_wdt_resume() will return NULL, leading to a NULL pointer
dereference afterward.
Set the platform device driver data in msc313e_wdt_probe().
