REGRESSION: ThinkPad W530 dim backlight with recent changes introduced in Linux 6.1.24

Due to recent commit a5b2781dcab2c77979a4b8adda781d2543580901 , I'm
facing an issue where the backlight is dimmer than before
in comparison to the backlight pre-commit on my Thinkpad W530.

Downgrading to an older kernel version fixes the issue.

I also realise that this recent commit replaces the intel_backlight
folder in /sys/class/backlight with acpi_video0.
It is also worth mentioning that I'm using Nouveau on my W530. Below
are the screenshots highlighting the issue.
