dell_laptop created a non-working backlight driver before nvidia is loaded, that leads to the system can't adjust the display brightness.
[Fix]
The patch prevents platform driver(dell_laptop) from creating backlight driver after win8.

[Where problems could occur]
The assumption of the backlight control is that after win8 all laptops backlight are controlled by either ACPI or native graphic driver. It impact the laptops that do not follow the assumption and will lead to broken backlight interface. |

[Impact]
There are some new patches for new method to decide which backlight driver should be registered introduced since 6.1. And we backport some of them to 6.0-oem kernel which are not enough to solved all backlight issues.
1. dell_laptop created a non-working backlight driver before nvidia is loaded, that leads to the system can't adjust the display brightness.
2. acpi_backlight0 sometimes will be generated together with intel_backlight.
[Fix]
Below 2 commits prevent the acpi_backlight from being registered automatically
e506731c8f35 ACPI: video: Make acpi_backlight=video work independent from GPU driver
78dfc9d1d1ab ACPI: video: Add auto_detect arg to __acpi_video_get_backlight_type()
