Static structure micro_bl_props, having type backlight_properties, is
used only once, when it is passed as the last argument to function
devm_backlight_device_register(). devm_backlight_device_register() is
defined with its last parameter being declared constant. Hence make
micro_bl_props itself constant as well.
Issue found with Coccinelle.
Did you do any review to see if this pattern occurs in other backlight
drivers (it looks to me like the same pattern appears in
rave-sp-backlight.c... do the tools bring that one out as well).
