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 drivers/dma/pl330.c | 53 ++++++++++++++++++++++++++++++++++++--------------- 1 file changed, 38 insertions(+), 15 deletions(-) -- 1.7.9.5
