Subject: [PATCH 02/18] ledtrig-blkdev: Add build infra for block device LED trigger
Date: Fri, 3 Sep 2021 15:45:32 -0500 [thread overview]
Message-ID: <20210903204548.2745354-3-arequipeno@gmail.com> (raw)
In-Reply-To: <20210903204548.2745354-1-arequipeno@gmail.com>
Add files:
* ledtrig-blkdev-core.c - trigger components that are always built in
* ledtrig-blkdev.c - trigger components that can be built as a module
* ledtrig-blkdev.h - common declatarions
Add Kconfig options - CONFIG_LEDTRIG_BLKDEV (visible, tristate) and
CONFIG_LEDTRIG_BLKDEV_CORE (hidden, boolean)
Make CONFIG_LEDTRIG_BLKDEV select CONFIG_LEDTRIG_BLKDEV_CORE, so built-in
portion of the trigger is enabled when trigger is built-in or modular
