The patch titled
serial: copy UART properties of UPF_FIXED_TYPE ports provisioned using early_serial_setup
has been removed from the -mm tree. Its filename was
serial-copy-uart-properties-of-upf_fixed_type-ports-provisioned-using-early_serial_setup.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: serial: copy UART properties of UPF_FIXED_TYPE ports provisioned using early_serial_setup
From: Shmulik Ladkani <shmulik@xxxxxxxxx>
Augment the UPF_FIXED_TYPE logic, which currently applies to UART ports
provisioned using platform_device_register.
The suggested patch applies same logic into 'serial8250_register_ports',
making UART ports provisioned using early_serial_setup inherit their
properties from the uart_config entry.
