Subject: [PATCH 11/14] net: spider_net: Fix the size used in a
'dma_free_coherent()' call
Git-commit: 36f28f7687a9ce665479cce5d64ce7afaa9e77ae
Patch-mainline: v5.9-rc1
References: git-fixes
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")
