From a2c68c62dba7acc1de5dd6a6141484d9c12844fe Mon Sep 17 00:00:00 2001 From: phk Date: Sat, 25 Sep 1999 16:21:39 +0000 Subject: This patch clears the way for removing a number of tty related fields in struct cdevsw: d_stop moved to struct tty. d_reset already unused. d_devtotty linkage now provided by dev_t->si_tty. These fields will be removed from struct cdevsw together with d_params and d_maxio Real Soon Now. The changes in this patch consist of: initialize dev->si_tty in *_open() initialize tty->t_stop remove devtotty functions rename ttpoll to ttypoll a few adjustments to these changes in the generic code a bump of __FreeBSD_version add a couple of FreeBSD tags --- sys/dev/snp/snp.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'sys/dev/snp') diff --git a/sys/dev/snp/snp.c b/sys/dev/snp/snp.c index 7563686..e30b293 100644 --- a/sys/dev/snp/snp.c +++ b/sys/dev/snp/snp.c @@ -82,9 +82,9 @@ snpdevtotty (dev) struct cdevsw *cdp; cdp = devsw(dev); - if (cdp == NULL) - return (NULL); - return ((*cdp->d_devtotty)(dev)); + if (cdp && cdp->d_flags & D_TTY) + return (dev->si_tty); + return (NULL); } #define SNP_INPUT_BUF 5 /* This is even too much,the maximal -- cgit v1.1
