[PATCH] drm/amd/display: fix dp_dsc_clock_en_read() debugfs function

[Dan Carpenter]

The other debugfs functions should probably be updated as well...  I
just did this one as an example of how these functions are normally
implemented.

There are some other warnings we could look at as well.

regards,
