Subject: [PATCH v2 0/4] DMA: PL330: Fix mem leaks and balance probe/remove 

The first 2 patches of this series fix memory leaks because the memory
allocated for peripheral channels and DMA descriptors were not getting
freed.

The last 2 patches balance the module's remove function.

This series depends on "61c6e7531d3b66b3 ........DMA: PL330: Check the
pointer returned by kzalloc" which is on slave-dma's "fixes" branch. 
Hence slave-dma tree's "next" branch was merged with "fixes" and 
applied patch at [1] to fix the build error.

[1] http://permalink.gmane.org/gmane.linux.kernel.next/24274

Changes since v1:
 - Protect only list_add_tail with spin_locks
 - Return EBUSY from remove if channel is in use
 - unregister dma_device in remove
 
Inderpal Singh (4):
  DMA: PL330: Free memory allocated for peripheral channels
  DMA: PL330: Change allocation method to properly free  DMA
    descriptors
  DMA: PL330: Balance module remove function with probe
  DMA: PL330: unregister dma_device in module's remove function
