Description

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().
