gryphon-led-module: fix error handling
...
The dev_get_drvdata/platform_get_drvdata functions do not return an

not support obsolete Linux versions. Check the return value of
gpiod_direction_output

...
To be able to dim the LED from user-space
we need to export an API. This is done

a file which handles hexadecimal numbers.
