Specifically this block adding code +depending on the LED subsystem. + +This is made even harder because CONFIG_V4L2_FWNODE is selected, +not depended on so it itself cannot depend on another subsystem without +editing all the Kconfig symbols selecting it to also list the dependency +and there are many of such symbols. + +Adding a "select LED_CLASS if NEW_LEDS" to CONFIG_V4L2_FWNODE leads +to Kconfig erroring out with "error: recursive dependency detected!". + +To fix this dependency mess, change the V4L2_FWNODE and V4L2_ASYNC +(which V4L2_FWNODE selects) Kconfig symbols from tristate to bools and +link their code into videodev.ko instead of making them separate modules. + +This will allow using IS_REACHABLE(LED_CLASS) for the new LED integration +code without needing to worry that it expands to 0 in some places and +1 in other places because some of the code being builtin vs modular. + +On x86_64 this leads to the following size changes for videodev.ko + +[hans@shalem linux]$ size drivers/media/v4l2-core/videodev.ko + +Before: + text data bss dec hex filename + 218206 14395 2448 235049 39629 drivers/media/v4l2-core/videodev.ko +After: + text data bss dec hex filename + 243213 17615 2456 263284 40474 drivers/media/v4l2-core/videodev.ko + +So (as expected) there is some increase in size here, but it +really is not that much. + +And the uncompressed no-debuginfo .ko file disk-usage actually shrinks +by 17 KiB (comparing the slightly larger videodev.ko against the +3 original modules) and loading time will also be better. + +Acked-by: Linus Walleij +Signed-off-by: Hans de Goede +Patchset: cameras +--- + drivers/media/v4l2-core/Kconfig | 4 ++-- + drivers/media/v4l2-core/Makefile | 4 ++-- + drivers/media/v4l2-core/v4l2-async.c | 17 ++++------------- + drivers/media/v4l2-core/v4l2-dev-priv.h | 19 +++++++++++++++++++ + drivers/media/v4l2-core/v4l2-dev.c | 8 ++++++++ + drivers/media/v4l2-core/v4l2-fwnode.c | 6 ------ + 6 files changed, 35 insertions(+), 23 deletions(-) + create mode 100644 drivers/media/v4l2-core/v4l2-dev-priv.h + +diff --git a/drivers/media/v4l2-core/Kconfig b/drivers/media/v4l2-core/Kconfig +index 348559bc24689..73574d9460105 100644 +--- a/drivers/media/v4l2-core/Kconfig ++++ b/drivers/media/v4l2-core/Kconfig +@@ -68,11 +68,11 @@ config V4L2_FLASH_LED_CLASS + When in doubt, say N. + + config V4L2_FWNODE +- tristate ++ bool + select V4L2_ASYNC + + config V4L2_ASYNC +- tristate ++ bool + + # Used by drivers that need Videobuf modules + config VIDEOBUF_GEN +diff --git a/drivers/media/v4l2-core/Makefile b/drivers/media/v4l2-core/Makefile +index 41d91bd10cf28..8c5a1ab8d939a 100644 +--- a/drivers/media/v4l2-core/Makefile ++++ b/drivers/media/v4l2-core/Makefile +@@ -15,7 +15,9 @@ videodev-objs := v4l2-dev.o v4l2-ioctl.o v4l2-device.o v4l2-fh.o \ + + # Please keep it alphabetically sorted by Kconfig name + # (e. g.
