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/isa/ad1848/ad1848.c | 4 ++-- sound/isa/cs423x/cs4231.c | 4 ++-- sound/isa/cs423x/cs4236.c | 4 ++-- sound/isa/es1688/es1688.c | 4 ++-- sound/isa/sb/sb16_csp.c | 2 +- sound/isa/sb/sb_mixer.c | 2 +- 6 files changed, 10 insertions(+), 10 deletions(-) (limited to 'sound/isa') diff --git a/sound/isa/ad1848/ad1848.c b/sound/isa/ad1848/ad1848.c index 593c6e959afe..47bffe623105 100644 --- a/sound/isa/ad1848/ad1848.c +++ b/sound/isa/ad1848/ad1848.c @@ -95,8 +95,8 @@ static int snd_ad1848_probe(struct device *dev, unsigned int n) if (error < 0) goto out; - strlcpy(card->driver, "AD1848", sizeof(card->driver)); - strlcpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); + strscpy(card->driver, "AD1848", sizeof(card->driver)); + strscpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); if (!thinkpad[n]) snprintf(card->longname, sizeof(card->longname), diff --git a/sound/isa/cs423x/cs4231.c b/sound/isa/cs423x/cs4231.c index 2135963eba78..bcbea6962d7e 100644 --- a/sound/isa/cs423x/cs4231.c +++ b/sound/isa/cs423x/cs4231.c @@ -95,8 +95,8 @@ static int snd_cs4231_probe(struct device *dev, unsigned int n) if (error < 0) goto out; - strlcpy(card->driver, "CS4231", sizeof(card->driver)); - strlcpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); + strscpy(card->driver, "CS4231", sizeof(card->driver)); + strscpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); if (dma2[n] < 0) snprintf(card->longname, sizeof(card->longname), diff --git a/sound/isa/cs423x/cs4236.c b/sound/isa/cs423x/cs4236.c index fa3c39cff5f8..fb9d8a4b7084 100644 --- a/sound/isa/cs423x/cs4236.c +++ b/sound/isa/cs423x/cs4236.c @@ -405,8 +405,8 @@ static int snd_cs423x_probe(struct snd_card *card, int dev) if (err < 0) return err; } - strlcpy(card->driver, chip->pcm->name, sizeof(card->driver)); - strlcpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); + strscpy(card->driver, chip->pcm->name, sizeof(card->driver)); + strscpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); if (dma2[dev] < 0) snprintf(card->longname, sizeof(card->longname), "%s at 0x%lx, irq %i, dma %i", diff --git a/sound/isa/es1688/es1688.c b/sound/isa/es1688/es1688.c index 64610571a5e1..766ab43aaf77 100644 --- a/sound/isa/es1688/es1688.c +++ b/sound/isa/es1688/es1688.c @@ -133,8 +133,8 @@ static int snd_es1688_probe(struct snd_card *card, unsigned int n) if (error < 0) return error; - strlcpy(card->driver, "ES1688", sizeof(card->driver)); - strlcpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); + strscpy(card->driver, "ES1688", sizeof(card->driver)); + strscpy(card->shortname, chip->pcm->name, sizeof(card->shortname)); snprintf(card->longname, sizeof(card->longname), "%s at 0x%lx, irq %i, dma %i", chip->pcm->name, chip->port, chip->irq, chip->dma8); diff --git a/sound/isa/sb/sb16_csp.c b/sound/isa/sb/sb16_csp.c index 270af863e198..8635a2b6b36b 100644 --- a/sound/isa/sb/sb16_csp.c +++ b/sound/isa/sb/sb16_csp.c @@ -388,7 +388,7 @@ static int snd_sb_csp_riff_load(struct snd_sb_csp * p, return err; /* fill in codec header */ - strlcpy(p->codec_name, info.codec_name, sizeof(p->codec_name)); + strscpy(p->codec_name, info.codec_name, sizeof(p->codec_name)); p->func_nr = func_nr; p->mode = le16_to_cpu(funcdesc_h.flags_play_rec); switch (le16_to_cpu(funcdesc_h.VOC_type)) { diff --git a/sound/isa/sb/sb_mixer.c b/sound/isa/sb/sb_mixer.c index 3f703b4a304d..5de5506e7e60 100644 --- a/sound/isa/sb/sb_mixer.c +++ b/sound/isa/sb/sb_mixer.c @@ -482,7 +482,7 @@ int snd_sbmixer_add_ctl(struct snd_sb *chip, const char *name, int index, int ty ctl = snd_ctl_new1(&newctls[type], chip); if (! ctl) return -ENOMEM; - strlcpy(ctl->id.name, name, sizeof(ctl->id.name)); + strscpy(ctl->id.name, name, sizeof(ctl->id.name)); ctl->id.index = index; ctl->private_value = value; if ((err = snd_ctl_add(chip->card, ctl)) < 0) -- cgit
