2024-06-26backlight: lm3509_bl: Fix early returns in for_each_child_of_node()Javier Carrasco
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().

Note that all graphical boot-up logos are freed during late kernel initialization, hence a copy must be made for later use.

2024-06-18fbdev: vesafb: Detect VGA compatibility from screen info's VESA attributesThomas Zimmermann
Test the vesa_attributes field in struct screen_info for compatibility with VGA hardware. Vesafb currently tests bit 1 in screen_info's capabilities field which indicates a 64-bit lfb address and is unrelated to VGA compatibility. Section 4.4 of the Vesa VBE 2.0 specifications defines that bit 5 in the mode's attributes field signals VGA compatibility. The mode is compatible with VGA hardware if the bit is clear. In that case, the driver can access VGA state of the VBE's underlying hardware. The vesafb driver uses this feature to program the color LUT in palette modes. Without, colors might be incorrect. The problem got introduced in commit 89ec4c238e7a ("[PATCH] vesafb: Fix incorrect logo colors in x86_64"). It incorrectly stores the mode attributes in the screen_info's capabilities field and updates vesafb accordingly. Later, commit 5e8ddcbe8692 ("Video mode probing support for the new x86 setup code") fixed the screen_info, but did not update vesafb. Color output still tends to work, because bit 1 in capabilities is usually 0. Besides fixing the bug in vesafb, this commit introduces a helper that reads the correct bit from screen_info.

2024-05-10backlight: mp3309c: Fix LEDs flickering in PWM modeFlavio Suligoi
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.
