[ Upstream commit 0ee7828 ] Since priv->rx_mapping[i] is maped in moxart_mac_open(), we should unmap it from moxart_mac_stop(). Fixes 2 warnings. 1. During error unwinding in moxart_mac_probe(): "goto init_fail;", then moxart_mac_free_memory() calls dma_unmap_single() with priv->rx_mapping[i] pointers zeroed.

When flushing, individual set elements are disabled in the next generation via the ->flush callback. Catchall elements are not disabled. This is incorrect and may lead to double-deactivations of catchall elements which then results in memory leaks: WARNING: CPU: 1 PID: 3300 at include/net/netfilter/nf_tables.h:1172 nft_map_deactivate+0x549/0x730 CPU: 1 PID: 3300 Comm: nft Not tainted 6.5.0-rc5+ #60 RIP: 0010:nft_map_deactivate+0x549/0x730 [..] ? nft_map_deactivate+0x549/0x730 nf_tables_delset+0xb66/0xeb0 (the warn is due to nft_use_dec() detecting underflow).
