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/i2c/i2c.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sound/i2c') diff --git a/sound/i2c/i2c.c b/sound/i2c/i2c.c index a684faa771ef..847e3b6ca601 100644 --- a/sound/i2c/i2c.c +++ b/sound/i2c/i2c.c @@ -84,7 +84,7 @@ int snd_i2c_bus_create(struct snd_card *card, const char *name, list_add_tail(&bus->buses, &master->buses); bus->master = master; } - strlcpy(bus->name, name, sizeof(bus->name)); + strscpy(bus->name, name, sizeof(bus->name)); err = snd_device_new(card, SNDRV_DEV_BUS, bus, &ops); if (err < 0) { snd_i2c_bus_free(bus); @@ -108,7 +108,7 @@ int snd_i2c_device_create(struct snd_i2c_bus *bus, const char *name, if (device == NULL) return -ENOMEM; device->addr = addr; - strlcpy(device->name, name, sizeof(device->name)); + strscpy(device->name, name, sizeof(device->name)); list_add_tail(&device->list, &bus->devices); device->bus = bus; *rdevice = device; -- cgit
