To be more exact I do:
  const char *dev_name = filp->f_path.dentry->d_parent->d_name.name;


If the sysctl table is shared between all network devices, the last
registered node will set the ->parent.

So accessing /proc/sys/net/ipv4/conf/$DEVNAME/$CTL will access $CTL
for the last network device registered not for $DEVNAME.
