Subject: [PATCH v2 03/15] leds: trigger: blkdev: Add functions needed by block changes
Date: Thu,  9 Sep 2021 17:25:01 -0500	[thread overview]
Message-ID: <20210909222513.2184795-4-arequipeno@gmail.com> (raw)
In-Reply-To: <20210909222513.2184795-1-arequipeno@gmail.com>

Add ledtrig_blkdev_disk_init() and ledtrig_blkdev_disk_cleanup()
placeholders.  (Function bodies depend on block subsystem changes
in next commit.)
