* tty: serial: 21285: stop using the unused[] variable from struct uart_portGreg Kroah-Hartman2019-12-191-10/+45
| | | | | | | | | | | | | | | | | | | | | | | | Much like the samsung_tty driver (now I know where they copied the idea from), the 21285 uart driver uses 2 bytes from the "unused" array of struct uart_port to keep tx/rx enabled/disabled state. Those fields are going away (they were never really needed in the first place), so fix up the 21285 driver by another horrible hack. Instead of creating a whole structure for just 2 bytes, just use two bits from the private_data pointer instead, as that pointer is never used. The two bits reflect if tx/rx is now enabled/disabled. Astute readers will note that once rx is disabled, nothing ever seems to turn it back on, making one wonder if anyone has ever done this.

| | | | | | | | | | | | | | | | The SUPPORT_SYSRQ ifdeffery is not nice as: - May create misunderstanding about sizeof(struct uart_port) between different objects - Prevents moving functions from serial_core.h - Reduces readability (well, it's ifdeffery - it's hard to follow) In order to remove SUPPORT_SYSRQ, has_sysrq variable has been added.

Initialise it in driver's probe and remove ifdeffery. In contrast to 8250/8250_of, legacy_serial on powerpc does fill (struct plat_serial8250_port). The reason is likely that it's done on device_initcall(), not on probe. So, 8250_core is not yet probed. Propagate value from platform_device on 8250 probe - in case powepc legacy driver it's initialized on initcall, in case 8250_of it will be initialized later on of_platform_serial_setup().
