Subject: [PATCH v2] media: v4l2-core: Fix memory leak in v4l2_fwnode_parse_link
Date: Fri, 19 Jun 2026 13:41:30 +0530 [thread overview]
Message-ID: <20260619081129.18485-2-birenpandya@gmail.com> (raw)
In v4l2_fwnode_parse_link(), the remote endpoint fwnode reference is
acquired using fwnode_graph_get_remote_endpoint(). This reference is
properly released in the error paths, but it is leaked on the success
path.
Add the missing fwnode_handle_put() before returning 0 to prevent the
reference leak.

Changes in v2:
- Resend because the v1 patch was lost in transit and did not appear on lore.kernel.org, causing CI to fail looking for the message ID. No code changes.
