Jingoo Han c512794cad backlight: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.  This is a cosmetic change to
make the code simpler and enhance the readability.

Jingoo Han 281ea16aa8 backlight: lms501kf03: use spi_get_drvdata and spi_set_drvdata
Use the wrapper functions for getting and setting the driver data using
spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
can directly pass a struct spi_device.
