net: myri10ge: fix memory leaks [ Upstream commit 20fb7c7a39b5c719e2e619673b5f5729ee7d2306 ] In myri10ge_probe(), myri10ge_alloc_slices() is invoked to allocate slices related structures. Later on, myri10ge_request_irq() is used to get an irq. However, if this process fails, the allocated slices related structures are not deallocated, leading to memory leaks. To fix this issue, revise the target label of the goto statement to 'abort_with_slices'. Signed-off-by: Wenwen Wang <firstname.lastname@example.org> Signed-off-by: David S.
