Build results:

Error log:
In file included from <command-line>:
drivers/gpu/drm/i915/display/intel_backlight.c: In function 'scale':
include/linux/compiler_types.h:536:45: error: call to '__compiletime_assert_666' declared with attribute error: clamp() low limit source_min greater than high limit source_max
536 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

The code itself did not change. I strongly suspect that the minmax changes
trigger the problem. Indeed, the build passes after
