commit fbd1ec000213c8b457dd4fb15b6de9ba02ec5482 upstream.
The is_visible function expects the permissions associated with an
attribute of the sysfs group or 0 if an attribute is not visible.
Change the code to return the attribute permissions when the attribute
should be visible which resolves the warning:
Attribute calibrate: Invalid permissions 01
Fixes: cc12ba1872c6 ("Input: ili210x - optionally show calibrate sysfs attribute")
