Subject: [PATCH 0/3] media: i2c: Adopt scope-based fwnode_handle_put
Date: Tue, 16 Jun 2026 04:00:52 +0530 [thread overview]
Message-ID: <20260615223055.39953-1-birenpandya@gmail.com> (raw)
This series updates the firmware node parsing logic across three highly active
V4L2 I2C sensor drivers (ov5640, imx290, and imx219) to utilize the modern
__free(fwnode_handle) scoped guard macro introduced in <linux/cleanup.h>.
By binding the lifecycle of the fwnode_handle directly to the variable's scope,
we eliminate the need for manual fwnode_handle_put() calls. This permanently
removes the risk of subtle early-free or missing-put memory leaks in
error-handling paths and establishes a cleaner pattern for newly merged
drivers to follow.
