Subject[PATCH 1/2] net: spider_net: Fix the size used in a 'dma_free_coherent()' call
Date
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")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

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