[ Upstream commit 1e0b72a2a6432c0ef67ee5ce8d9172a7c20bba25 ]
The mlxsw_sp2_nve_vxlan_learning_set() function is supposed to return
zero on success or negative error codes. So it needs to be type int
instead of bool.

[ Upstream commit f990874b1c98fe8e57ee9385669f501822979258 ]
If of_clk_add_provider() fails in ca8210_register_ext_clock(),
it calls clk_unregister() to release priv->clk and returns an
error. However, the caller ca8210_probe() then calls ca8210_remove(),
where priv->clk is freed again in ca8210_unregister_ext_clock(). In
this case, a use-after-free may happen in the second time we call
clk_unregister().
Fix this by removing the first clk_unregister(). Also, priv->clk could
be an error code on failure of clk_register_fixed_rate(). Use
IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().
