backlight: qcom-wled: Pass number of elements to read to read_u32_array
[ Upstream commit e29e24bdabfeddbf8b1a4ecac1af439a85150438 ]
of_property_read_u32_array takes the number of elements to read as last
argument. This does not always need to be 4 (sizeof(u32)) but should
instead be the size of the array in DT as read just above with
of_property_count_elems_of_size.
To not make such an error go unnoticed again the driver now bails
accordingly when of_property_read_u32_array returns an error.
Surprisingly the indentation of newlined arguments is lining up again
after prepending `rc = `.
