Subject: [PATCH] interconnect: core: fix error return code of icc_link_destroy()
Date: Sat, 6 Mar 2021 05:28:57 -0800 [thread overview]
Message-ID: <20210306132857.17020-1-baijiaju1990@gmail.com> (raw)
When krealloc() fails and new is NULL, no error return code of
icc_link_destroy() is assigned.
To fix this bug, ret is assigned with -ENOMEM hen new is NULL.
