HSI: ssi_protocol: fix potential resource leak in ssip_pn_open()
ssip_pn_open() claims the HSI client's port with hsi_claim_port(). When hsi_register_port_event() gets some error and returns a negetive value, the HSI client's port should be released with hsi_release_port(). Fix it by calling hsi_release_port() when hsi_register_port_event() fails. Signed-off-by: Jianglei Nie <niejianglei2021@163.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
