Dave,

Here are two more small fixes intended for 2.6.36.  One is a one-liner
(kmalloc->kzalloc) that prevents a potential information leak.
The other is a small fix that skips firmware reloads (a workaround
for firmware problems) while a scan is in progress in order to avoid
the stack trace cited in the commit log.

Please let me know if there are problems!

Thanks,

John
