From 0d64b568fcd48b133721c1d322e7c51d85eb12df Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 13 Dec 2009 12:42:56 +0100 Subject: ALSA: sound/isa/gus: Correct code taking the size of a pointer sizeof(share_id) is just the size of the pointer. On the other hand, block->share_id is an array, so its size seems more appropriate. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // Signed-off-by: Julia Lawall Signed-off-by: Takashi Iwai --- sound/isa/gus/gus_mem.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'sound') diff --git a/sound/isa/gus/gus_mem.c b/sound/isa/gus/gus_mem.c index 661205c4dcea..af888a022fc0 100644 --- a/sound/isa/gus/gus_mem.c +++ b/sound/isa/gus/gus_mem.c @@ -127,7 +127,8 @@ static struct snd_gf1_mem_block *snd_gf1_mem_share(struct snd_gf1_mem * alloc, !share_id[2] && !share_id[3]) return NULL; for (block = alloc->first; block; block = block->next) - if (!memcmp(share_id, block->share_id, sizeof(share_id))) + if (!memcmp(share_id, block->share_id, + sizeof(block->share_id))) return block; return NULL; } -- cgit v1.2.3
