[PATCH] ixp4xx_eth: Delete an unnecessary check before the function call "dma_pool_destroy"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 16 Nov 2015 12:23:23 +0100

The dma_pool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
