Usage of the iterator outside of the list_for_each_entry is considered harmful. https://lkml.org/lkml/2022/2/17/1032 Do not reference the loop variable outside of the loop, by rearranging the orders of execution. Instead of performing search loop and checking outside the loop if the end of the list was hit and no matching element was found, the execution is performed inside the loop upon a successful match followed by a goto statement to the next step, therefore no condition has to be performed after the loop has ended.

2022-03-18serial: 8250: fix XOFF/XON sending when DMA is usedIlpo Järvinen
When 8250 UART is using DMA, x_char (XON/XOFF) is never sent to the wire. After this change, x_char is injected correctly. Create uart_xchar_out() helper for sending the x_char out and accounting related to it. It seems that almost every driver does these same steps with x_char. Except for 8250, however, almost all currently lack .serial_out so they cannot immediately take advantage of this new helper. The downside of this patch is that it might reintroduce the problems some devices faced with mixed DMA/non-DMA transfer which caused revert f967fc8f165f (Revert "serial: 8250_dma: don't bother DMA with small transfers"). However, the impact should be limited to cases with XON/XOFF (that didn't work with DMA capable devices to begin with so this problem is not very likely to cause a major issue, if any at all).

We tested RS485 function on an EVB which has SC16IS752, after finishing the test, we started the RS232 function test, but found the RTS is still working in the RS485 mode. That is because both startup and shutdown call port_update() to set the EFCR_REG, this will not clear the RS485 bits once the bits are set in the reconf_rs485().

2022-03-18serial: SERIAL_SUNPLUS should depend on ARCH_SUNPLUSGeert Uytterhoeven
Sunplus serial ports are only present on Sunplus SoCs. Hence add a dependency on ARCH_SUNPLUS, to prevent asking the user about this driver when configuring a kernel without Sunplus SoC support.

2022-03-18serial: samsung_tty: do not unlock port->lock for uart_write_wakeup()Jiri Slaby
The commit c15c3747ee32 (serial: samsung: fix potential soft lockup during uart write) added an unlock of port->lock before uart_write_wakeup() and a lock after it. It was always problematic to write data from tty_ldisc_ops::write_wakeup and it was even documented that way. We fixed the line disciplines to conform to this recently. So if there is still a missed one, we should fix them instead of this workaround. On the top of that, s3c24xx_serial_tx_dma_complete() in this driver still holds the port->lock while calling uart_write_wakeup(). So revert the wrap added by the commit above.

2022-03-18kgdboc: fix return value of __setup handlerRandy Dunlap
__setup() handlers should return 1 to obsolete_checksetup() in init/main.c to indicate that the boot option has been handled. A return of 0 causes the boot option/value to be listed as an Unknown kernel parameter and added to init's (limited) environment strings. So return 1 from kgdboc_option_setup(). Unknown kernel command line parameters "BOOT_IMAGE=/boot/bzImage-517rc7 kgdboc=kbd kgdbts=", will be passed to user space. Run /sbin/init as init process with arguments: /sbin/init with environment: HOME=/ TERM=linux BOOT_IMAGE=/boot/bzImage-517rc7 kgdboc=kbd kgdbts= Link: lore.kernel.org/r/64644a2f-4a20-bab3-1e15-3b2cdd0defe3@omprussia.ru Fixes: 1bd54d851f50 ("kgdboc: Passing ekgdboc to command line causes panic") Fixes: f2d937f3bf00 ("consoles: polling support, kgdboc") Cc: He Zhe <zhe.he@windriver.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Jiri Slaby <jirislaby@kernel.org> Cc: kgdb-bugreport@lists.sourceforge.net Cc: Jason Wessel <jason.wessel@windriver.com> Cc: Daniel Thompson <daniel.thompson@linaro.org> Cc: Douglas Anderson <dianders@chromium.org> Cc: linux-serial@vger.kernel.org Reported-by: Igor Zhbanov <i.zhbanov@omprussia.ru> Reviewed-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Link: https://lore.kernel.org/r/20220309033018.17936-1-rdunlap@infradead.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

It is recommended by the Synopsis databook to issue a DCTL.CSftReset when reconnecting from a device-initiated disconnect routine.
