Subject: [PATCH v3] media: i2c: imx290: Drop manual fwnode_handle_put() via scope-based cleanup
Date: Wed, 8 Jul 2026 18:46:37 +0530 [thread overview]
Message-ID: <20260708131637.35132-2-birenpandya@gmail.com> (raw)
In-Reply-To: <20260616081517.44685-3-birenpandya@gmail.com>
Utilize the __free(fwnode_handle) scoped guard macro from
<linux/cleanup.h> to automate the lifecycle management of the endpoint
fwnode in imx290_parse_dt().
This safely ties the release of the fwnode_handle to its compiler
scope, allowing us to drop the manual fwnode_handle_put() call and
removing the risk of missed puts if new early returns are added in
the future.
