Hi Greg,
Thank you for pointing that out.
There is no difference from the previous submissions. I was studying the drivers/staging codebase and followed the Documentation/filesystems/sysfs.rst recommendation without being aware that this exact cleanup had already been discussed and rejected recently.
I apologize for the oversight and for not thoroughly checking the lore archives before submitting.
I will drop this patch. Thanks, Park Tae-sun

The sysfs documentation (Documentation/filesystems/sysfs.rst) recommends using sysfs_emit() instead of sprintf() in sysfs show() callbacks.
Replace the remaining sprintf() calls in the fade_##__dir##_show() macro and color_show() callback with sysfs_emit().
This follows the standard kernel practice and existing use of sysfs_emit() in other Greybus sysfs show functions.
No functional change.
How is this different from past patches that have attempted to change this?
thanks,
