This should use the new fb_tft api instead of trying to look like a tty device. That framework is merged in the staging-next branch of the staging.git kernel tree and will show up in 4.1-rc1. Please port this driver to that api and submit a patch for me to take for the staging tree so that we don't have one-off devices like this. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
