tty: tty_ldisc: Fix some kernel-doc related misdemeanours
- Functions must follow directly on from their headers - Demote non-conforming kernel-doc header - Ensure notes have unique section names - Provide missing description for 'reinit' Fixes the following W=1 kernel build warning(s): drivers/tty/tty_ldisc.c:158: warning: cannot understand function prototype: 'int tty_ldisc_autoload = IS_BUILTIN(CONFIG_LDISC_AUTOLOAD); ' drivers/tty/tty_ldisc.c:199: warning: Function parameter or member 'ld' not described in 'tty_ldisc_put' drivers/tty/tty_ldisc.c:260: warning: duplicate section name 'Note' drivers/tty/tty_ldisc.c:717: warning: Function parameter or member 'reinit' not described in 'tty_ldisc_hangup' Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Jiri Slaby <jirislaby@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20201112105857.2078977-2-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
