Subject: [PATCH v3 1/4] drm: add devm release action
Date: Mon, 22 Apr 2024 12:27:53 +0530 [thread overview]
Message-ID: <20240422065756.294679-2-aravind.iddamsetty@linux.intel.com> (raw)
In-Reply-To: <20240422065756.294679-1-aravind.iddamsetty@linux.intel.com>
In scenarios where drm_dev_put is directly called by driver we want to
release devm_drm_dev_init_release action associated with struct
drm_device.
v2: Directly expose the original function, instead of introducing a
helper (Rodrigo)
v3: add kernel-doc (Maxime Ripard)
