Removes unused function genericbl_limit_intensity() in
backlight/generic_bl.c.

This eliminates the following warning in backlight/generic_bl.c:
drivers/video/backlight/generic_bl.c:59:6: warning: no previous prototype for ‘genericbl_limit_intensity’ [-Wmissing-prototypes]

Hi Eric,

Originally, genericbl_limit_intensity() was added by you.
(commit: bfdcaa3 "lcd: add corgibl_limit_intensity() to corgi_lcd")

Currently, genericbl_limit_intensity() is not called anywhere
in mainline kernel. Can we remove this genericbl_limit_intensity()?


Best regards,
Jingoo Han
