From: Kairui Song <kasong@tencent.com>

This series fixes two bugs of backing device setting:

- ZRAM should reject using a zero sized (or the uninitialized ZRAM
  device itself) as the backing device.
- Fix backing device leaking when removing a uninitialized ZRAM
  device.

Kairui Song (2):
  zram: refuse to use zero sized block device as backing device
  zram: fix uninitialized ZRAM not releasing backing device
