Fwd: Does not work backlight on Chromebook XE303C12 with Kernel version 6.3.4

Fwd: Does not work backlight on Chromebook XE303C12 with Kernel version 6.3.4

[Bagas Sanjaya]

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> I did check it by flashlight. Even with all available backlights drivers compiled as modules it does not work. With Kernel version 5.15.106 backlight works fine.
> Kernels for Chomebook uses dtb files that have some backlight config set (used gpio), like exynos5250-snow-common.dtsi and dmesg of 6.3.4 gives some gpio warnings. Maybe cause in it.

See bugzilla for the full thread and attached dmesg & kernel config.

Anyway, I'm adding it to regzbot:

#regzbot introduced: v5.15..v6.3 https://bugzilla.kernel.org/show_bug.cgi?id=217489
#regzbot title: Chromebook XE303C12 backlight stopped working with gpio warnings

Thanks.

The reporter confirms [1] that he doesn't have this regression (for now) on
v6.3.x (not reproducible), so I mark it as inconclusive:

#regzbot inconclusive: not a kernel regression

Thanks.
