This is a double negative. Just say "if (dprivate) {". Actually just
reverse the test and remove the bogus printk. Say:
if (!dprivate)
return 0;
But *actually* just remove the test entirely because it can never be
NULL. Same for virtpci_driver_attr_store().
Btw, if you have the smatch cross function database set up then you can
figure out this sort of thing by using:
$ smdb.py virtpci_driver_attr_store
It says that:
fs/sysfs/file.c | sysfs_kf_write | (struct sysfs_ops)->store | PARAM_VALUE | 0 | $ | 4096-2117777777777777777
So this is called from sysfs_kf_write() and parameter zero is a valid
pointer.
