[PATCH 3/4] proc: kmalloc struct pde_opener

[PATCH 3/4] proc: kmalloc struct pde_opener

[Alexey Dobriyan]

kzalloc is too much, half of the fields will be reinitialized anyway.

If proc file doesn't have ->release hook (some still do not), clearing
is unnecessary because it will be freed immediately.
