From b28dbcb379e6a7f80262c2732a57681b1ee548ca Mon Sep 17 00:00:00 2001 From: Jianglei Nie Date: Mon, 5 Sep 2022 15:48:01 +0800 Subject: [PATCH] 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.
