## Description

In the Linux kernel, the following vulnerability has been resolved:  dmaengine: omap-dma: fix dma_pool resource leak in error paths  The dma_pool created by dma_pool_create() is not destroyed when dma_async_device_register() or of_dma_controller_register() fails, causing a resource leak in the probe error paths.  Add dma_pool_destroy() in both error paths to properly release the allocated dma_pool resource.
