Commit 0e125a5f ("tty: amba-pl011: define flag register bits for ZTE device") changes earlycon function pl011_putc() to use a pointer to uart_amba_port. This causes a regression when earlycon is enabled, because uart_amba_port is not available yet at earlycon time. Let's revert the change on pl011_putc() to fix the regression. The earlycon support for ZTE device can probably be added later by declaring a new earlycon setup function with a vendor specific compatible.

For now, these fall back to regular (dark) colors. It'd be tempting to replace blink with bright backgrounds, as permitted by CGA/VGA -- we already muck with the other programmable bit (foreground brightness vs 512 character font). This would bring vgacon in line with fbcon, which doesn't support blink anywhere but on some drivers renders that bit as bright background. If that is done, this commit should be amended to be one of ways of setting that bit.

Commit 761ed4a9 ("tty: serial_core: convert uart_close to use tty_port_close") created a case where a port used for a console does not get shutdown on tty closing. Then a call to uart_tx_stopped() segfaults because the tty is NULL. This could be fixed to restore old behavior, but we also want to allow tty_ports to work without a tty attached. So this change to allow a NULL tty_struct is needed either way.

Since commit 18dfef9c ("serial: atmel: convert to irq handling provided mctrl-gpio"), interrupts from GPIOs are not disabled any more when the serial port is closed, leading to an oops when the one of the input pin is toggled (CTS/DSR/DCD/RNG). This is only the case if those pins are used as GPIOs, i.e. declared like that: usart1: serial@f8020000 { /* CTS and DTS will be handled by GPIO */ status = "okay"; rts-gpios = <&pioB 17 GPIO_ACTIVE_LOW>; cts-gpios = <&pioB 16 GPIO_ACTIVE_LOW>; dtr-gpios = <&pioB 14 GPIO_ACTIVE_LOW>; dsr-gpios = <&pioC 31 GPIO_ACTIVE_LOW>; rng-gpios = <&pioB 12 GPIO_ACTIVE_LOW>; dcd-gpios = <&pioB 15 GPIO_ACTIVE_LOW>; }; That's because modem interrupts used to be freed in atmel_shutdown(). After commit 18dfef9c ("serial: atmel: convert to irq handling provided mctrl-gpio"), this code was just removed. Calling atmel_disable_ms() disables the interrupts and everything works fine again. Tested on at91sam9g35-cm (This patch doesn't apply on -stable kernels, fixes for 4.4 and 4.7 will be sent after this one is applied.)
