    backlight: da9052: Fully initialize backlight_properties during probe
    
    [ Upstream commit 0285e9efaee8276305db5c52a59baf84e9731556 ]
    
    props is stack allocated and the fields that are not explcitly set
    by the probe function need to be zeroed or we'll get undefined behaviour
    (especially so power/blank states)!
