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/usb/mixer_quirks.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sound/usb/mixer_quirks.c') diff --git a/sound/usb/mixer_quirks.c b/sound/usb/mixer_quirks.c index df036a359f2f..abad1d61a536 100644 --- a/sound/usb/mixer_quirks.c +++ b/sound/usb/mixer_quirks.c @@ -2725,7 +2725,7 @@ static int snd_pioneer_djm_controls_info(struct snd_kcontrol *kctl, struct snd_c if (info->value.enumerated.item >= count) info->value.enumerated.item = count - 1; name = group->options[info->value.enumerated.item].name; - strlcpy(info->value.enumerated.name, name, sizeof(info->value.enumerated.name)); + strscpy(info->value.enumerated.name, name, sizeof(info->value.enumerated.name)); info->type = SNDRV_CTL_ELEM_TYPE_ENUMERATED; info->count = 1; info->value.enumerated.items = count; -- cgit v1.2.3
