Subject: [PATCH] misc/pvpanic: fix panic on accessing sysfs entries

Commit 394febc9d0a6 ("misc/pvpanic: Make 'pvpanic_probe()' resource managed")
removed dev_set_drvdata from the probe function and accessing sysfs entries
from userspace is causing a panic in the kernel (pi = dev_get_drvdata(dev) ->
pi is NULL).
