Christophe JAILLET e9f0177590 dmaengine: mediatek: mtk-hsdma: Fix a resource leak in the error handling path of the probe function 
commit 33cbd54dc515cc04b5a603603414222b4bb1448d upstream.

'mtk_hsdma_hw_deinit()' should be called in the error handling path of the
probe function to undo a previous 'mtk_hsdma_hw_init()' call, as already
done in the remove function.

Satendra Singh Thakur d33803aef7 dmaengine: mediatek: hsdma_probe: fixed a memory leak when devm_request_irq fails 
[ Upstream commit 1ff95243257fad07290dcbc5f7a6ad79d6e703e2 ]

When devm_request_irq fails, currently, the function
dma_async_device_unregister gets called. This doesn't free
the resources allocated by of_dma_controller_register.
Therefore, we have called of_dma_controller_free for this purpose.
