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/emu10k1/emu10k1.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sound/pci/emu10k1/emu10k1.c') diff --git a/sound/pci/emu10k1/emu10k1.c b/sound/pci/emu10k1/emu10k1.c index 29b7720d7961..353934c88cbd 100644 --- a/sound/pci/emu10k1/emu10k1.c +++ b/sound/pci/emu10k1/emu10k1.c @@ -168,9 +168,9 @@ static int snd_card_emu10k1_probe(struct pci_dev *pci, } #endif - strlcpy(card->driver, emu->card_capabilities->driver, + strscpy(card->driver, emu->card_capabilities->driver, sizeof(card->driver)); - strlcpy(card->shortname, emu->card_capabilities->name, + strscpy(card->shortname, emu->card_capabilities->name, sizeof(card->shortname)); snprintf(card->longname, sizeof(card->longname), "%s (rev.%d, serial:0x%x) at 0x%lx, irq %i", -- cgit v1.2.3
