From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 36f28f7687a9ce665479cce5d64ce7afaa9e77ae ]
Update the size used in 'dma_free_coherent()' in order to match the one
used in the corresponding 'dma_alloc_coherent()', in
'spider_net_init_chain()'.
Fixes: d4ed8f8d1fb7 ("Spidernet DMA coalescing")
