[PATCH 5.11 326/775] dmaengine: owl-dma: Fix a resource leak in the remove function

From: Greg Kroah-Hartman
Date: Mon Mar 01 2021 - 19:13:58 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 1f0a16f04113f9f0ab0c8e6d3abe661edab549e6 ]

A 'dma_pool_destroy()' call is missing in the remove function.
Add it.

This call is already made in the error handling path of the probe function.
