Summary
net: altera-tse: fix skb leak on DMA mapping error in tse_start_xmit()
Details

In the Linux kernel, the following vulnerability has been resolved:

net: altera-tse: fix skb leak on DMA mapping error in tsestartxmit()

When dmamapsingle() fails in tsestartxmit(), the function returns NETDEVTXOK without freeing the skb. Since NETDEVTXOK tells the stack the packet was consumed, the skb is never freed, leaking memory on every DMA mapping failure.

Add devkfreeskb_any() before returning to properly free the skb.
