| H A D | tty_baudrate.c | 4545b069 Mon Sep 27 08:35:16 CDT 2021 Pali Rohár <pali@kernel.org> tty: baudrate: Explicit usage of B0 for encoding input baudrate
Function tty_termios_input_baud_rate() checks IBSHIFT & CBAUD against B0
constant to determinate if input speed equals to output speed. So do same
B0 check also in tty_termios_encode_baud_rate() function to make these two
functions compatible.
Currently macro B0 is defined to 0 so there is no functional change.
This change just make code more explicit to show that Bnnn constants are
stored in CBAUD.
