Gcc 4.6.2 complains that "end" can be used without being initialized:
drivers/video/backlight/lp855x_bl.c: In function ‘lp855x_init_registers’:
drivers/video/backlight/lp855x_bl.c:78:32: warning: ‘end’ may be used uninitialized in this function [-Wuninitialized]
drivers/video/backlight/lp855x_bl.c:67:12: note: ‘end’ was declared here
I've modified the function to return invalid if we don't recognize the
id string.
