From 75b1a8f9d62e50f05d0e4e9f3c8bcde32527ffc1 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 4 Jan 2021 09:17:34 -0800 Subject: ALSA: Convert strlcpy to strscpy when return value is unused strlcpy is deprecated. see: Documentation/process/deprecated.rst Change the calls that do not use the strlcpy return value to the preferred strscpy. Done with cocci script: @@ expression e1, e2, e3; @@ - strlcpy( + strscpy( e1, e2, e3); This cocci script leaves the instances where the return value is used unchanged. After this patch, sound/ has 3 uses of strlcpy() that need to be manually inspected for conversion and changed one day. $ git grep -w strlcpy sound/ sound/usb/card.c: len = strlcpy(card->longname, s, sizeof(card->longname)); sound/usb/mixer.c: return strlcpy(buf, p->name, buflen); sound/usb/mixer.c: return strlcpy(buf, p->names[index], buflen); Miscellenea: o Remove trailing whitespace in conversion of sound/core/hwdep.c Link: https://lore.kernel.org/lkml/CAHk-=wgfRnXz0W3D37d01q3JFkr_i_uTL=V6A6G1oUZcprmknw@mail.gmail.com/ Signed-off-by: Joe Perches Acked-by: Mark Brown Link: https://lore.kernel.org/r/22b393d1790bb268769d0bab7bacf0866dcb0c14.camel@perches.com Signed-off-by: Takashi Iwai --- sound/drivers/opl3/opl3_oss.c | 2 +- sound/drivers/opl3/opl3_synth.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'sound/drivers') diff --git a/sound/drivers/opl3/opl3_oss.c b/sound/drivers/opl3/opl3_oss.c index 7bf0d5f3fedd..c82c7c1c0714 100644 --- a/sound/drivers/opl3/opl3_oss.c +++ b/sound/drivers/opl3/opl3_oss.c @@ -97,7 +97,7 @@ void snd_opl3_init_seq_oss(struct snd_opl3 *opl3, char *name) return; opl3->oss_seq_dev = dev; - strlcpy(dev->name, name, sizeof(dev->name)); + strscpy(dev->name, name, sizeof(dev->name)); arg = SNDRV_SEQ_DEVICE_ARGPTR(dev); arg->type = SYNTH_TYPE_FM; if (opl3->hardware < OPL3_HW_OPL3) { diff --git a/sound/drivers/opl3/opl3_synth.c b/sound/drivers/opl3/opl3_synth.c index 08c10ac9d6c8..97d30a833ac8 100644 --- a/sound/drivers/opl3/opl3_synth.c +++ b/sound/drivers/opl3/opl3_synth.c @@ -290,7 +290,7 @@ int snd_opl3_load_patch(struct snd_opl3 *opl3, } if (name) - strlcpy(patch->name, name, sizeof(patch->name)); + strscpy(patch->name, name, sizeof(patch->name)); return 0; } -- cgit v1.2.3
