Lenny Szubowicz 9eb91ea09e Revert "tty/serial: 8250: Sort drivers in Makefile" ... JIRA: https://issues.redhat.com/browse/RHEL-69911 Upstream Status: RHEL9 only This reverts cs9 commit 9291d2620e. cs9 commit 9291d2620e is a backport of upstream commit 66ebe67d1b68 ("tty/serial: 8250: Sort drivers in Makefile") Changing the order that source files are compiled and linked into the 8250 serial line driver also changes the order that the init routines in that driver are invoked. This can result in ttySn devices being enumerated differently, depending on configuration details. In the specific case of this JIRA, in RHEL 9.4: 1.1 Routine pciserial_init_one in drivers/tty/serial/8250/8250_pci.c configures a PCI serial port as ttyS0. 1.2 Routine dw8250_probe in drivers/tty/serial/8250/8250_dw.c configures two serial ports enumerated by ACPI as ttyS1, ttyS2. But in RHEL 9.5 where 8250_dw.c is moved ahead of 8250_pci.c: 2.1 Routine dw8250_probe in drivers/tty/serial/8250/8250_dw.c configures two serial ports enumerated by ACPI as ttyS0, ttyS1. 2.2 Routine pciserial_init_one in drivers/tty/serial/8250/8250_pci.c configures a PCI serial port as ttyS2. If at all possible, RHEL should avoid such user visible changes in a minor release. Therefore, for the duration of RHEL 9.x only, revert this change. But for RHEL 10, stay with the upstream change.
