Subject: [PATCH net-next] net: microchip: sparx5: Fix uninitialized variable
 in vcap_path_exist()

The "eport" variable needs to be initialized to NULL for this code to
work.

Fixes: 814e7693207f ("net: microchip: vcap api: Add a storage state to a VCAP rule")

Probably you had CONFIG_INIT_STACK_ALL=y in your .config for this to
pass testing.
