serial-uartlite: Change logic how console_port is setup

2019-11-13T13:54:15Z

Change logic how console_port is setup by using CON_ENABLED flag instead of index. There will be unique uart_console structure that's why code can't use id for console_port assignment.

tty: serial: uartlite: use clk_disable_unprepare to match clk_prepare_enable

2019-11-04T16:45:32Z

The driver uses clk_prepare_enable in ulite_probe but uses clk_unprepare in ulite_remove, which does not match. Replace clk_unprepare with clk_disable_unprepare to fix it.

serial: uartlite: fix exit path null pointer

2019-10-04T13:02:46Z

Call uart_unregister_driver() conditionally instead of unconditionally, only if it has been previously registered. This uses driver.state, just as the sh-sci.c driver does. Fixes this null pointer dereference in tty_unregister_driver(), since the 'driver' argument is null: general protection fault: 0000 [#1] PREEMPT SMP KASAN PTI RIP: 0010:tty_unregister_driver+0x25/0x1d0 Fixes: 238b8721a554 ("[PATCH] serial uartlite driver") Signed-off-by: Randy Dunlap Cc: stable Cc: Peter Korsgaard Link: https://lore.kernel.org/r/9c8e6581-6fcc-a595-0897-4d90f5d710df@infradead.org Signed-off-by: Greg Kroah-Hartman
