Yes, it's already used "mmc_of_parse".
You can see "slot quirks 'disable-wp' is deprecated".
Since the properties was included in slot regs before using "mmc_of_parse".
So we chosen to print the message "deprecated" to prevent the developer's confusion.
At this time, actually, i think there are no developers who confused this.
I will consider more about this patch.
Thanks!
