If we register a "leds-gpio" platform device for GPIO pins that do not exist we get a -EPROBE_DEFER and the probe will be tried again later. If there is no driver to provide that pin we will poll forever and also create a lot of log messages. So check if that GPIO driver is configured, if so it will come up eventually. If not, we exit our probe function early and do not even bother registering the "leds-gpio". This method was chosen over "Kconfig depends" since this way we can add support for more devices and GPIO backends more easily without "depends":ing on all GPIO backends.

Clang complains that devm_add_action() takes a parameter with a wrong type: warning: cast from 'void (*)(struct mutex *)' to 'void (*)(void *)' converts to incompatible function type [-Wcast-function-type-strict] err = devm_add_action(dev, (void (*)(void *))mutex_destroy, &is31->lock); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 warning generated. It appears that the commit e1af5c81 ("leds: is31fl319x: Fix devm vs. non-devm ordering") missed two things: - whilst the commit mentions devm_add_action_or_reset() the actual change utilised devm_add_action() call by mistake - strictly speaking the parameter is not compatible by type Fix both issues by switching to devm_add_action_or_reset() and adding a wrapper for mutex_destroy() call.

I defined 2 leds in the device tree, in the 1st led node, the max-brightness is set to 248, while in the 2nd led node, I mis-spelled the max-brightness to max-brighttness, but the driver is still able to get the max-brightness 248 for the 2nd node, that is because the led structure is not cleared before parsing each child node. pwmleds { compatible = "pwm-leds"; pwm-green { ... max-brightness = <248>; }; pwm-red { ... max-brighttness = <128>; }; Signed-off-by:Hui Wang <hui.wang@canonical.com> Signed-off-by:

Hans de Goede authored
Add a generic [devm_]led_get() method which can be used on both devicetree and non devicetree platforms to get a LED classdev associated with a specific function on a specific device, e.g. the privacy LED associated with a specific camera sensor. Note unlike of_led_get() this takes a string describing the function rather then an index. This is done because e.g. camera sensors might have a privacy LED, or a flash LED, or both and using an index approach leaves it unclear what the function of index 0 is if there is only 1 LED. This uses a lookup-table mechanism for non devicetree platforms. This allows the platform code to map specific LED class_dev-s to a specific device,function combinations this way. For devicetree platforms getting the LED by function-name could be made to work using the standard devicetree pattern of adding a -names string array to map names to the indexes. Reviewed-by:
