1e3b097012 backlight: jornada720: Minimise code duplication and handle errors better 
Rickard Strandqvi's ran a code analysis application which found that
jornada_lcd_get_contrast(() and jornada_lcd_set_contrast() contained
some code duplication (calling the same functions during various
code execution paths) and failed to return errors in a consistent
manner.  This patch aims to simplify the code, coercing it into
behaving at a level expected of a driver in the Linux kernel.

20c225cbb6 backlight: jornada720: use pr_err()/pr_info() instead of printk() 
Use pr_err()/pr_info() instead of printk() to allow dynamic debugging.
The pr_fmt prefix for pr_ macros is used.  Also fix checkpatch warnings as
below:

WARNING: Prefer pr_err(... to printk(KERN_ERR, ...
WARNING: Prefer pr_info(... to printk(KERN_INFO, ...
