    Subject[PATCH v2 7/7] backlight: progear: use pr_err instead of printk
    Date
    This patch uses pr_err instead of printk to allow dynamic debugging.
    The pr_fmt prefix for pr_ macros is used. It also fixes checkpatch
    warnings as below:

    WARNING: printk() should include KERN_ facility level
