kernel.h: split out panic and oops helpers

2021-07-01T18:06:04Z

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

leds: lgm: Fix up includes

2021-06-23T22:55:41Z

This driver is including the legacy GPIO header but the only thing it is using from that header is the wrong define for GPIOF_DIR_OUT. Fix it up by using GPIO_LINE_DIRECTION_OUT and including the correct consumer and driver headers. Cc: Amireddy Mallikarjuna reddy Signed-off-by: Linus Walleij Signed-off-by: Pavel Machek

leds: ktd2692: Fix an error handling path

2021-06-23T22:55:28Z

In 'ktd2692_parse_dt()', if an error occurs after a successful 'regulator_enable()' call, we should call 'regulator_enable()'. This is the same in 'ktd2692_probe()', if an error occurs after a successful 'ktd2692_parse_dt()' call. Instead of adding 'regulator_enable()' in several places, implement a resource managed solution and simplify the remove function accordingly.

leds: as3645a: Fix error return code in as3645a_parse_node()

2021-06-23T20:14:39Z

Return error code -ENODEV rather than '0' when the indicator node can not be found. Fixes: a56ba8fbcb55 ("media: leds: as3645a: Add LED flash class driver") Reported-by: Hulk Robot Acked-by: Sakari Ailus Signed-off-by: Zhen Lei Signed-off-by: Pavel Machek

leds: turris-omnia: add missing MODULE_DEVICE_TABLE

2021-06-23T20:11:26Z

This patch adds missing MODULE_DEVICE_TABLE definition which generates correct modalias for automatic loading of this driver when it is built as an external module. Reported-by: Hulk Robot Signed-off-by: Zou Wei Signed-off-by: Pavel Machek

leds: lp55xx: Initialize enable GPIO direction to output

2021-06-23T20:09:35Z

The "Convert to use GPIO descriptors" commit changed the initialization of the enable GPIO from GPIOF_DIR_OUT to GPIOD_ASIS. This breaks systems where the GPIO does not default to output. Changing the enable initialization to GPIOD_OUT_LOW. Signed-off-by: Doug Zobel Signed-off-by: Pavel Machek

leds: lm36274: Add missed property.h

2021-05-30T21:03:48Z

It appears that property.h has been included in some configurations implicitly, but in some it's not and hence build may fail. Add missed property.h explicitly.

leds: el15203000: Make error handling more robust

It's easy to miss necessary clean up, e.g. firmware node reference counting, during error path in ->probe(). Make it more robust by moving to a single point of return. Signed-off-by: Andy Shevchenko Signed-off-by: Pavel Machek
