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/pci/ice1712/juli.c | 2 +- sound/pci/ice1712/psc724.c | 4 ++-- sound/pci/ice1712/quartet.c | 2 +- sound/pci/ice1712/wm8776.c | 2 +- 4 files changed, 5 insertions(+), 5 deletions(-) (limited to 'sound/pci/ice1712') diff --git a/sound/pci/ice1712/juli.c b/sound/pci/ice1712/juli.c index e57a55cebc5a..f0f8324b08b6 100644 --- a/sound/pci/ice1712/juli.c +++ b/sound/pci/ice1712/juli.c @@ -413,7 +413,7 @@ static struct snd_kcontrol *ctl_find(struct snd_card *card, { struct snd_ctl_elem_id sid = {0}; - strlcpy(sid.name, name, sizeof(sid.name)); + strscpy(sid.name, name, sizeof(sid.name)); sid.iface = SNDRV_CTL_ELEM_IFACE_MIXER; return snd_ctl_find_id(card, &sid); } diff --git a/sound/pci/ice1712/psc724.c b/sound/pci/ice1712/psc724.c index 7aa3f92040d0..82cf365cda10 100644 --- a/sound/pci/ice1712/psc724.c +++ b/sound/pci/ice1712/psc724.c @@ -189,12 +189,12 @@ static void psc724_set_jack_state(struct snd_ice1712 *ice, bool hp_connected) /* notify about master speaker mute change */ memset(&elem_id, 0, sizeof(elem_id)); elem_id.iface = SNDRV_CTL_ELEM_IFACE_MIXER; - strlcpy(elem_id.name, "Master Speakers Playback Switch", + strscpy(elem_id.name, "Master Speakers Playback Switch", sizeof(elem_id.name)); kctl = snd_ctl_find_id(ice->card, &elem_id); snd_ctl_notify(ice->card, SNDRV_CTL_EVENT_MASK_VALUE, &kctl->id); /* and headphone mute change */ - strlcpy(elem_id.name, spec->wm8776.ctl[WM8776_CTL_HP_SW].name, + strscpy(elem_id.name, spec->wm8776.ctl[WM8776_CTL_HP_SW].name, sizeof(elem_id.name)); kctl = snd_ctl_find_id(ice->card, &elem_id); snd_ctl_notify(ice->card, SNDRV_CTL_EVENT_MASK_VALUE, &kctl->id); diff --git a/sound/pci/ice1712/quartet.c b/sound/pci/ice1712/quartet.c index 0e3e04aa9faf..0dfa093f7dca 100644 --- a/sound/pci/ice1712/quartet.c +++ b/sound/pci/ice1712/quartet.c @@ -771,7 +771,7 @@ static struct snd_kcontrol *ctl_find(struct snd_card *card, { struct snd_ctl_elem_id sid = {0}; - strlcpy(sid.name, name, sizeof(sid.name)); + strscpy(sid.name, name, sizeof(sid.name)); sid.iface = SNDRV_CTL_ELEM_IFACE_MIXER; return snd_ctl_find_id(card, &sid); } diff --git a/sound/pci/ice1712/wm8776.c b/sound/pci/ice1712/wm8776.c index d96008df880d..6eda86119dff 100644 --- a/sound/pci/ice1712/wm8776.c +++ b/sound/pci/ice1712/wm8776.c @@ -38,7 +38,7 @@ static void snd_wm8776_activate_ctl(struct snd_wm8776 *wm, unsigned int index_offset; memset(&elem_id, 0, sizeof(elem_id)); - strlcpy(elem_id.name, ctl_name, sizeof(elem_id.name)); + strscpy(elem_id.name, ctl_name, sizeof(elem_id.name)); elem_id.iface = SNDRV_CTL_ELEM_IFACE_MIXER; kctl = snd_ctl_find_id(card, &elem_id); if (!kctl) -- cgit v1.2.3
