Worked on the geerlingguy/linux repository to address a regression in GPIO resource management within the kernel module. Focused on improving device driver stability by ensuring that GPIO resources acquired through devm_gpiod_get_array() are properly released using devm_release_action in devm_gpiod_put_array(). This change prevented resource leaks that could lead to resource exhaustion in long-running systems. The solution involved careful handling of resource management primitives in C, with an emphasis on kernel development best practices. By validating the fix and enhancing devres handling, the work contributed to more reliable GPIO handling and improved overall system stability in the Linux kernel environment.
