Hello, Heiko.
I think that function l5f31188_display_enable() is needed to wrap up function
l5f31188_display_on().
Function l5f31188_display_enable() is used as an interface to external side,
especially to MIPI DSI driver. But function l5f31188_display_on() is used as an
internal function in this driver.
Moreover, because they have different input argument types, it cannot be simply
replacable.
Thank you for your reply.
Best regards,
Hyungwon Hwang
