The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >>From 641a41dbba217ee5bd26abe6be77f8cead9cd00e Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Tue, 30 Oct 2018 15:13:35 +0900 Subject: serial: sh-sci: Fix could not remove dev_attr_rx_fifo_timeout This patch fixes an issue that the sci_remove() could not remove dev_attr_rx_fifo_timeout because uart_remove_one_port() set the port->port.type to PORT_UNKNOWN.
