Native backlight regressed from logarithmic to linear scale

[2.] Full description of the problem/report:

With the new default of video.use_native_backlight=0 (commit 
v3.16-rc1~30^2~2^3), my Thinkpad T510 backlight has become very difficult 
to control near the low end of the scale.  The lowest setting now turns 
the backlight completely off, but the second-lowest setting is too bright.  
Meanwhile, the difference between the highest several settings is nearly 
imperceptible.

This happened because /sys/class/backlight/acpi_video0/brightness (which 
has now disappeared) used a different scale than 
/sys/class/intel_backlight/brightness; the relationship between 
acpi_video0 and intel_backlight was not linear.  I measured the exact 
relationship as follows:

acpi    intel
0       52
1       87
2       139
3       174
4       226
5       261
6       313
7       435
8       591
9       800
10      1078
11      1461
12      1914
13      2557
14      3358
15      4437

The relationship is close to logarithmic; a good fit is intel = 
60*(4/3)^acpi, or acpi = log_{4/3} (intel/60).  It’s well known that 
perceived brightness varies logarithmically with physical luminance 
(Fechner’s law), so it’s no surprise that the acpi_video0 scale was more 
useful.

Since the kernel no longer uses ACPI to do this translation, it should do 
the translation itself.
