2024-06-26backlight: lm3509_bl: Fix early returns in for_each_child_of_node()Javier Carrasco1-2/+1
The for_each_child_of_node() macro automatically decrements the child refcount at the end of every iteration. On early exits, of_node_put() must be used to manually decrement the refcount and avoid memory leaks. The scoped version of the macro accounts for such early breaks, fixing the early exits without the need for explicit calls to of_node_put().

to 0 These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

2024-05-10backlight: mp3309c: Fix LEDs flickering in PWM modeFlavio Suligoi1-5/+0
The mp3309 has two configuration registers, named according to their address (0x00 and 0x01). In the second register (0x01), the bit DIMS (Dimming Mode Select) must be always 0 (zero), in both analog (via I2C commands) and PWM dimming mode. In the initial driver version, the DIMS bit was set in PWM mode and reset in analog mode. But if the DIMS bit is set in pwm dimming mode and other devices are connected on the same I2C bus, every I2C commands on the bus generates a flickering on the LEDs powered by the mp3309c. This change concerns the chip initialization and does not impact any existing device-tree configuration.

Remove the field fb_blank from struct backlight_properties and remove all code that still sets or reads it. Backlight blank status is now tracked exclusively in struct backlight_properties.state. The core backlight code keeps the fb_blank and state fields in sync, but doesn't do anything else with fb_blank. Several drivers initialize fb_blank to FB_BLANK_UNBLANK to enable the backlight. This is already the default for the state field. So we can delete the fb_blank code from core and drivers and rely on the state field.
