[PATCH] firmware_class: Avoid pending list corruption

From: Imran Khan
Date: Wed Jan 25 2017 - 07:46:34 EST

Remove firmware buffer from pending list when it is freed.
Once the buffer is free kmalloc can allocate the same slab
object for some other user but as the buffer is still there
in the pending list, we end up with multiple users of the
same slab object using it in different contexts.
