[PATCH] net: sgi: ioc3-eth: Fix the size used in some 'dma_free_coherent()' calls
From: Christophe JAILLET
Date: Sun Aug 02 2020 - 09:52:13 EST
Update the size used in 'dma_free_coherent()' in order to match the one
used in the corresponding 'dma_alloc_coherent()'.
Fixes: 369a782af0f1 ("net: sgi: ioc3-eth: ensure tx ring is 16k aligned.")
