[PATCH v5 3/3] Staging: zram: Fix decrement of variable by calling bdput()

From: Rashika Kheria
Date: Mon Oct 28 2013 - 07:48:50 EST

As suggested by Jerome Marchand "The code in reset_store get the block device
(bdget_disk()) but it does not put it (bdput()) when it's done using it.
The usage count is therefor incremented but never decremented."

Hence, this patch introduces a call to bdput() to decrement the variable after usage.
