tty: mmc: sdio: use u8 for flag

Switch character types to u8. To conform to characters in the rest of the tty layer. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Ulf Hansson Cc: linux-mmc@vger.kernel.org Link: https://lore.kernel.org/r/20231206073712.17776-17-jirislaby@kernel.org Signed-off-by: Greg Kroah-Hartman

tty: make tty_operations::send_xchar accept u8 char

2023-12-08T11:02:37Z

tty_operations::send_xchar is one of the last users of 'char' type for characters in the tty layer. Convert it to u8 now.

tty: mmc: sdio_uart: switch sdio_in() to return u8

2023-12-08T11:02:37Z

sdio_in() returns a value returned from sdio_readb(). The latter returns u8. So should the former. Therefore, switch sdio_in() return type to u8 and all its callers too.

tty: Convert ->dtr_rts() to take bool argument

2023-01-19T15:04:35Z

Convert the raise/on parameter in ->dtr_rts() to bool through the callchain. The parameter is used like bool. In USB serial, there remains a few implicit bool -> larger type conversions because some devices use u8 in their control messages. In moxa_tiocmget(), dtr variable was reused for line status which requires int so use a separate variable for status.

tty: Convert ->carrier_raised() and callchains to bool

2023-01-19T15:04:35Z

Return boolean from ->carrier_raised() instead of 0 and 1. Make the return type change also to tty_port_carrier_raised() that makes the ->carrier_raised() call (+ cd variable in moxa into which its return value is stored). Also cleans up a few unnecessary constructs related to this change: return xx ? 1 : 0; -> return xx; if (xx) return 1; return 0; -> return xx; Reviewed-by: Jiri Slaby Acked-by: Ulf Hansson # For MMC Signed-off-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20230117090358.4796-7-ilpo.jarvinen@linux.intel.com Signed-off-by: Greg Kroah-Hartman
