| Subject: net: spider_net: Fix the size used in a 'dma_free_coherent()' call |
| |
| From: Christophe JAILLET <christophe.jaillet@wanadoo.fr> |
| |
| [ 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") |
