[PATCH 1/2] net: spider_net: Fix the size used in a 'dma_free_coherent()' call

From: Christophe JAILLET
Date: Sun Aug 02 2020 - 09:53:40 EST


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")

NOT compile tested, because I don't have the configuration for that
