2516ffac94 staging/ozwpan: info leak in oz_cdev_ioctl()
If we're not maxed out then oz_get_pd_list() leaves part of the "list"
struct uninitialized.  We should clear this so that no stack information
is leaked to userspace.

-> add static keyword to silence the warning and make sparse happy.

984a4a0378 staging: ozwpan: use tasklet_kill in device remove/release process
Some driver uses tasklet_disable in device remove/release process,
tasklet_disable will inc tasklet->count and return. If the tasklet
is not handled yet under some softirq pressure, the tasklet will be
placed on the tasklet_vec, never have a chance to be excuted. This might
lead to a heavy loaded ksoftirqd, wakeup with pending_softirq, but
tasklet is disabled. tasklet_kill should be used in this case.
